List of Tables xxii MX2800 STS-1 User Manual 61200659L1-1
Chapter 1 Introduction PRODUCT OVERVIEW The MX2800 STS-1 is a SONET multiplexer that consolidates T1 and E1 signals into an STS-1 signal. This unit provides a costeffective, versatile tool for combining independent T1s or E1s over the same STS-1 carrier. Embedded SNMP (simple network management protocol) and Telnet are available through the modem port using SLIP/PPP or through the 10BaseT ethernet port.
Chapter 1. Introduction The major features of the MX2800 STS-1 are as follows: • • • • • • • • • • • • • Built-in 1:1 redundancy Hot-swappable controller cards Independent, dual-load sharing, redundant power supplies Embedded SNMP and Telnet management through 10BaseT ethernet or SLIP/PPP dialup Detailed performance monitoring for local and remote units Simplified configuration through the VT-100 terminal menu structure Integrated V.
Chapter 1. Introduction STS-1 OVERVIEW The MX2800 STS-1 multiplexer delivers up to 28 T1s or 21 E1s via the SONET Synchronous Transport Signal Level One (STS-1) at a speed of 51.84 Mbps. This is a cost-effective way to provide T1/E1 signals without the need for costly and complex multi-level multiplexing/demultiplexing as in an M13 multiplexer. The T1/E1 signals can be directly multiplexed into the SONET STS-1 signal, allowing simplified add and drop functionality.
Chapter 1. Introduction compensation. Pointer adjustments allow the synchronous payload envelope (SPE) to float with respect to the SONET frame. The pointer is contained in the H1 and H2 bytes of the line overhead (LOH), and is a count of the number of bytes the J1 byte is away from the H3 byte, not including the transport overhead. When timing differences exist, dummy bytes are inserted into the SPE without affecting data.
Chapter 1. Introduction Unit Timing The MX2800 STS-1 multiplexer allows three timing methods. The first is LOOP timed, in which the multiplexer derives timing from the incoming STS-1 signal. A failure in this signal, such as a lossof-signal (LOS) or a loss-of-framing (LOF) will cause the unit to enter HOLDOVER (HO) mode for the duration of the receive signal defect. During HO, the unit will continue transmitting at the same rate as the receive signal prior to entering its defect condition.
Chapter 1. Introduction supports the MIB-II standard, RFC 1213, RFC 1595, and the ADTRAN Enterprise Specific MIB. MIB files are available at www.adtran.com. The term SNMP broadly refers to the message protocols used to exchange information between the network management system (NMS) and the managed devices, as well as to the structure of device management databases. SNMP has three basic components, the network manager, the agent, and the MIB.
Chapter 1. Introduction TL1 Transaction Language 1 (TL1) is an ASCII based language that supports both command-response and autonomous (NE) message generation. Commonly, TL1 is used over a X.25 packet network but is completely independent of any physical layer protocols. For the MX2800 STS-1, TL1 is implemented as a Telnet session running over either Ethernet or PPP. Only one TL1 Telnet connection can be active at a time.
Chapter 1. Introduction AVAILABLE OPTIONS The following optional equipment is available for use with the MX2800 STS-1. Contact your local distributor or the ADTRAN sales department for more information (see front section of this manual for phone number).

Figure 3-1 shows the CONFIGURATION menu and Figure 3-2 on page 3-2 shows the menu tree. Figure 3-1. Configuration Menu Detailed descriptions of the menu options shown in Figure 3-1 are given in the following sections.
Chapter 3. Configuration Line Length STS-1 Configuration Timing XCV Threshold Network Interface VT Mode Protection Configuration Active Controller Network Protection Max Switch Threshold Miscellaneous Loopback Timeout External Clock Configuration PRI Ext.
Chapter 3. Configuration NETWORK INTERFACE Select NETWORK INTERFACE to access the network configuration parameters (see Figure 3-3). Configure the MX2800 STS-1 network settings to match the STS-1 signal received from the service provider. Figure 3-3. Network Configuration Menu STS-1 Configuration Use the STS-1 CONFIGURATION selections described below to configure the STS-1 network settings to match your application.
Chapter 3. Configuration signal or reception of AIS will cause the unit to enter hold-over mode. The STS-1 receive signal must be valid for at least 10 seconds for the unit to exit hold-over mode and restore loop timing. When the unit is configured for FREE-RUN timing mode, timing is derived from a +/-20 ppm internal reference providing a SONET Minimum Clock (SMC). Setting the unit to EXTERNAL timing mode configures the unit to derive clocking from one of the two external sources selected in the PRI EXT.
Chapter 3. Configuration Setting The unit switches controller cards if... 1E-3 more than one out of every 1,000 bits received on the STS-1 contains a code violation. 1E-4 more than one out of every 10,000 bits received on the STS-1 contains a code violation. 1E-5 more than one out of every 100,000 bits received on the STS-1 contains a code violation. 1E-6 more than one out of every 1,000,000 bits received on the STS-1 contains a code violation.
Chapter 3. Configuration Network Protection Enable or disable the unit’s ability to automatically route information to the backup STS-1 in the event of a primary STS-1 failure. With NETWORK PROTECTION set to ENABLED, all information is automatically routed to the backup STS-1 in the event that the primary STS-1 fails. When NETWORK PROTECTION is set to DISABLED, the stand-by controller will be used to protect against failures of the circuitry on the active controller.
Chapter 3. Configuration External Clock Configuration PRI Ext. Clock and SEC Ext. Clock - When timing is set to external, these entries allow selection of the primary and secondary clock source. Any one of the 28 ports, so long as it is active, can be used. If the selected port does go into AIS or LOS, the selected clock becomes invalid.
Chapter 3. Configuration VT Interface #1-28 The VT Interface menu allows the user to map a Port (T1/E1) to a VT, activate/deactivate the T1 and E1 mapped to the VT, and to set the line coding, length, loopback detection, circuit protection, line ID string, and disable/enable the hairpin loopback. Configuration selections are described in the section following Figure 3-5. Figure 3-5. Configure VT Interface #1 Menu VT/Port Mapping Map a T1/E1 port to a VT. Any available port (1-28) can be mapped to a VT.

Tributary Loopback Test Analog Network An ANALOG NETWORK loopback test loops the selected T1/E1 back to the network (STS-1). The T1/E1 is completely de-multiplexed, looped back at the T1/E1 line interface unit (LIU) through the LIU drivers and receivers, and multiplexed back onto the STS-1 network stream. See Figure 6-4 for an illustration of this test.
Chapter 6. Diagnostics Digital Line/Net A DIGITAL LINE/NET loopback performs a loopback of the selected T1/E1 in both the network and local loop directions. Both loopbacks occur at the T1/E1 LIU. The network side loopback occurs deep into the LIU through the receiver, receive equalizer, transmit jitter attenuator, and finally, through the T1/E1 transmit drivers. See Figure 6-5 for an illustration of this test.
Chapter 6. Diagnostics CSU Loopback A CSU LOOPBACK enables the MX2800 STS-1 to generate a CSU loop-up pattern (001001…) towards the T1 CSU attached to the selected T1 line for six seconds. After six seconds have elapsed, the pattern will cease and incoming network traffic will be passed through to the CSU device. If the CSU device responded to the CSU loop-up pattern, it will return all data back towards the network. A loop-down pattern (0000100001….
Chapter 6. Diagnostics Only one T1 port may engage a CSU LOOPBACK, CSU LOOPBACK W/BERT, or a LINE BERT. If a CSU LOOPBACK, CSU LOOPBACK W/BERT, or a LINE BERT is already active at the time a new CSU LOOPBACK, CSU LOOPBACK W/BERT, or LINE BERT is selected, the former test will be terminated and the latter test will be engaged.

The end effect of this test is a loopback of all VT/Ports after passing through the STS-1 mapper and the LIU. The incoming STS-1 data is ignored and the outgoing STS-1 stream is looped back into the “AGC/Receive Equalizer Block” in the LIU.
Chapter 6. Diagnostics Digital Loopback A DIGITAL LOOPBACK loops the entire STS-1 back to the local loop side. The end effect of this test is a loopback of all VT/Ports after passing through the STS-1 mapper and partially through the LIU. The incoming STS-1 data is ignored and the outgoing STS-1 stream is substituted in its place just prior to entering the STS-1 encoder block of the LIU. This data will be processed through the “Transmit Clock Duty Cycle Adjust” PLL and the “HDB3/B3ZS Encoder” block.
Chapter 6. Diagnostics Metallic Diagnostics A METALLIC DIAGNOSTIC loopback test loops the entire STS-1 back to the local loop side. The end effect of this test is a loopback of all VT/Ports after being fully multiplexed and de-multiplexed to and from the STS-1 and passed through both directions of the LIU. During this test, the incoming STS-1 is disconnected from the STS-1 receiver and the outgoing STS-1 signal is substituted in its place. See Figure 6-14 for an illustration of this test.

Chapter 7 Circuit and Network Redundancy The MX2800 STS-1 provides backup measures of protection for both circuit and network failure. The following sections describe the three possible modes of operation: • • • Non-Redundant Mode, which offers no backup protection, is described on page 7-2. Circuit Failure Recovery Mode, which offers backup protection in the event of controller card failure, is described on page 7-3.
Chapter 7. Circuit and Network Redundancy NON-REDUNDANT MODE In Non-Redundant Mode, the MX2800 STS-1 houses only one controller card and only one network connection is available. There is no failure protection. In the event of a failure, an alarm is initiated and the front panel LEDs reflect the condition. See Figure 7-1 for an illustration. MX2800 STS-1 Figure 7-1. Non-Redundant Mode In this mode, the STS-1 must be connected to the IN and OUT jacks for NET A.
Chapter 7. Circuit and Network Redundancy CIRCUIT FAILURE RECOVERY MODE In Circuit Failure Recovery Mode, two controller cards are installed and a single STS-1 line is coming in (see Figure 7-2). In this mode, the MX2800 STS-1 can continue operating in the event of a controller card failure. When both cards are healthy, the primary card actively processes data while the secondary card stands by ready to take over if the first fails.
Chapter 7. Circuit and Network Redundancy Table 7-1. Configuration Requirements for Circuit Recovery Selection Path Recommended Setting Config > Network Interface > XCV Threshold 1E-3 (see the following note) Config > Network Interface > Network Protection Disabled Config > Network Interface > Max. Switch Threshold 3 Config > Network Interface > Min.
Chapter 7. Circuit and Network Redundancy In a case like this, the MX2800 STS-1 is able to automatically reroute NET B to CARD A. The configuration requirements for this mode are the same as the ones given for Circuit Failure Recovery Mode (see Table 7-1 on page 7-4) except for the NETWORK PROTECTION setting, which must be set to ENABLE. MX2800 STS-1 Figure 7-3.
Chapter 7.
Chapter 8 Power Loss Recovery The MX2800 STS-1 provides backup measures of protection for both power supply and power source failures. The following sections describe the possible modes of operation: • • • • 61200659L1-1 Non-Redundant Power Mode, which offers no backup protection, is described on page 8-2. Power Supply Recovery Mode, which offers backup protection in the event of power supply card failure, is described on page 8-3.
Chapter 8. Power Loss Recovery NON-REDUNDANT POWER MODE In Non-Redundant Power Mode, the MX2800 STS-1 houses only one power supply card and only one power source is available. There is no power failure protection. If a power supply card fails, then the unit is inoperable until the card is repaired or replaced. See Figure 8-1 for an illustration. MX2800 STS-1 Figure 8-1. Non-Redundant Power Mode Power supplies are hot-swappable.
Chapter 8. Power Loss Recovery POWER SUPPLY RECOVERY MODE In Power Supply Recovery Mode, two power supply cards are installed and connected to a single power source (see Figure 8-2). In this mode, the MX2800 STS-1 can continue to operate during a power supply failure, without interrupting service. The power supplies are load sharing, so either power supply can provide power for the entire unit.
Chapter 8. Power Loss Recovery POWER SUPPLY AND SOURCE RECOVERY MODE In this mode, two power supply cards are installed and are connected to two individual power sources. The MX2800 STS-1 handles any combination of power source or power supply failure. Much like the backup design for the controller cards, the MX2800 STS-1 is able to internally re-route the power source if a power supply card and the opposite power source fail.
Chapter 8. Power Loss Recovery BATTERY BACKUP MODE With the installation of the ADTRAN Power Supply/Battery Charger (PS/BC) and backup battery pack, the MX2800 STS-1 is able to continue operation without service interruption during a power outage. This PS/BC (P/N 4175043L2) provides -48 VDC to the MX2800 STS-1. It receives 115 VAC through a standard plug and wall socket. The PS/BC maintains the battery at peak charge (-48 V) at all times.

Chapter 9 Transaction Language 1 (TL1) INTRODUCTION Transaction Language 1 (TL1) is a BELLCORE standard used in the input and output messages that pass between Operations Systems (OS) and Network Elements (NE) in telecommunication networks. It was developed to standardize equipment surveillance and memory administration, and to test with a common format. This release of TL1 primarily supports the interactive and autonomous retrieval of system events as part of a valid TL1 session.
Chapter 9. Transaction Language 1 (TL1) management port enabled, a valid IP and gateway address, and a valid subnet mask. Once the Telnet connection is established, it is necessary to initiate a TL1 session. Establishing a TL1 session involves successful user authentication. Until a TL1 session is established, all commands other than those used to initiate or terminate a session will be denied (autonomous messaging is also disabled). Authentication involves the successful entry of a username/password pair.
Chapter 9. Transaction Language 1 (TL1) currently supports two types of acknowledgment messages: In Progress (IP) and All Right (OK). In Progress The IP acknowledgment message is usually generated as an interim response message to indicate that a message has been received and that the command is being executed.
Chapter 9. Transaction Language 1 (TL1) The MX2800 STS-1 specifically uses “quoted line(s)” in the response message of successfully executed RTRV-ALM commands. The quoted line format is as follows: :,,,,,… The NTFCNCDE field will contain one of the following values: • MN - Minor • MJ - Major • CR - Critical Refer to the condition types listed in Table 9-2 on page 9-10 (MX2800 STS-1 Alarm Events) for possible MX2800 STS-1 CONDTYPE codes.
Chapter 9. Transaction Language 1 (TL1) The MX2800 STS-1 specifically uses “quoted line(s)” in REPTALM and REPT-EVT autonomous messages.
Chapter 9. Transaction Language 1 (TL1) Areas of concentration for TL1 support in the MX2800 STS-1 include session initiation, termination, user account management, and system event reporting. Table 9-1 lists the commands currently supported by the MX2800 STS-1. Table 9-1.

Chapter 9. Transaction Language 1 (TL1) TL1 AUTONOMOUS MESSAGES Autonomous messages provide a mechanism for real time reporting of system events. Transmission of these messages is disabled by default and must be explicitly enabled. Although most events reported are alarms, some events are only informational. The VERB, MOD1, and MOD2 parameters of the message indicate what type of event has occurred. REPT-ALM indicates an alarm event. Table 9-2 lists possible autonomous messages for alarm events.

Appendix C.
Appendix D Glossary 10BaseT Ethernet connector which implements the IEEE standard on 24-gauge, unshielded twisted-pair wiring. AMI Alternate mark inversion. A bipolar line-coding format in T1 transmission systems whereby successive ones are alternately inverted. ANSI American National Standards Institute. A non-profit organization that coordinates voluntary standards activities in the United States.
Appendix D. Glossary BERT Bit error rate test. A test that uses any of a number of stress patterns to test T3, T1, FT1, and DDS circuits. bipolar A signal containing both positive and negative amplitude components. bipolar violation See BPV. bit A binary digit representing a signal, wave, or state as either a one or a zero. A bit is the smallest unit of information a computer can process. bit error The receipt of an encoded bit that differs from what was sent by the transmitter.
Appendix D. Glossary byte Generally, an 8-bit quantity of information. This term is used mainly in referring to parallel data transfer, semiconductor capacity, and data storage. carrier The provider of the telecommunication services to the customer site. Carriers can be local telephone companies, regional telephone companies, or any interexchange carrier such as AT&T, Sprint, or MCI. C-bit An overhead bit in the DS3 string not used for framing, parity, or alarm indication.
Appendix D. Glossary clocking An oscillator-generated signal that provides a timing reference for a transmission link. A clock provides signals used in a transmission system to control the timing of certain functions. The clock has two functions: (1) to generate periodic signals for synchronization, and (2) to provide a time base. CPE Customer premises equipment.
Appendix D. Glossary DCE Data communications equipment. Device that provides all the functions required for connection to telephone company lines and for converting signals between telephone lines and DTE. Also see DTE. DDS Digital data service. A private line digital service for transmitting data end-to-end at speeds of 2.4, 4.8, 9.6, and 56 kbps (and in some cases 19.2, 38.4, or 64 kbps).
Appendix D. Glossary DSU Data service unit. A device designed to transmit and receive digital data on digital transmission facilities. DTE Data terminal equipment. The end-user terminal or computer that plugs into the termination point (DCE) of a communications circuit. The main difference between the DCE and the DTE is that pins two and three are reversed. E1 Transmission rates of 2.048 Mbps are available on T1 communication lines. See also T1.
Appendix D. Glossary FDL Facility datalink. FDL bits provide overhead communication between the terminal equipment in ESF framing. gateway A device which enables information to be exchanged between two dissimilar systems or networks. host computer The primary or controlling computer in a multiple computer operation. idle code In a T3 circuit, an idle code consists of a sequence of 1100 over the entire payload bandwidth. in-band Signaling (dialing, diagnostics, management, configuration, etc.
Appendix D. Glossary LOS Loss of signal. Defined as a line state in which no pulses are received for 175 bit positions. M13 DS1/DS3 multiplexer that combines up to 28 DS1 channels into one DS3 channel. Uses two-stage, bit synchronous TDM. Mbps Megabits per second (one million bits per second). MIB Management information base. A database of network management information used by SNMP. modem Acronym for modulator/demodulator. Equipment that converts digital signals to and from analog signals.
Appendix D. Glossary NRZ Non return to zero. A mode in which the digital level is low for a 0 bit and high for a 1 bit, and does not return to zero between successive 1 bits. out-of-band Signaling that is separated from the channel carrying information (voice, data, video, etc.). Typically the separation is accomplished by a filter. The signaling includes dialing and other supervisory signals.
Appendix D. Glossary router A device that supports communications between networks. Routers are similar to bridges, with the exception that routers provide more functionality (such as finding the best route between networks and providing network management capabilities). service The provision of telecommunications to customers by a common carrier, administration, or private operating agency using voice, data, and/or video technologies. service provider A company that delivers or sells a telecom service.
Appendix D. Glossary T1 Transmission rates of 1.544 Mbps are available on T1 communication lines. Also referred to as digital signal level 1 (DS-1). See also E1. T3 Transmission rates of 44.736 Mbps are available on T3 communication lines. Also referred to as digital signal level 3 (DS-3). TDM Time division multiplexing. A technique for transmitting two or more signals at the same time over a single communication medium.
Appendix D. Glossary yellow alarm A T3 yellow alarm is an indication sent back toward the source of a failed transmit circuit in a DS3 two-way transmission path. The X-bits (X1 and X2) are set to zero.
