FXS-ID Configuration plate of the FXS-ID card has 12 channel status LEDs and one 4-position DIP switch for selecting from a number of different signaling types. Furthermore, the back plate also contains 12 test switches that can be used to “busy out” each channel individually. On the FXS-ID card itself, each individual channel has a 6-position DIP switch for setting transmit and receive line attenuation.
Setting the FXS Transmit and Receive Levels 8.3.3 Wink Delay Select Wink Delay to translate two-state wink-start signaling toward the T1 network to an FXS ringing with delayed wink for proceed-to-send digit indication. Upon detection of an incoming seizure from the T1 network, the AB2 applies ringing voltage to the FXS channel.
FXS-ID Configuration If your FXS voice channels require different attenuation level settings than the factory defaults, proceed as follows: 1. Release the two thumbscrews on the AB2 back plate and remove the plate (see Figure 8-2). 2. To remove the FXS-ID slide-in voice card, pull out the two card ejector latches simultaneously to release the card from the internal connector, then slide the card carefully out from the rear of the AB2 chassis (see Figure 8-2). 3.

FXS-ID Configuration informs the equipment to hang up. 8.6.1.3 Option 2. Wink-Start to Ground-Start Conversion Switch A OFF Switch B ON Switch C OFF POTS Interface This option provides a POTS (Plain Old Telephone Service) ground-start interface between the Access Bank II - SNMP and the PBX or other phone equipment. This avoids both-way call collisions (“glare”) on PBX trunks and gives the PBX a disconnect signal when the far-end party hangs up.
FXS Signaling Option Descriptions 8.6.1.6 Option 5. Wink-Start to Loop-Start Conversion with ANI/DNIS and Calling Party Disconnect Switch A ON Switch B OFF Switch C ON This option provides a loop-start interface between the AB2 and the PBX for voice mail/phone applications. E&M wink-start signaling and per-channel ringback tones are sent to the T1 line. Ringing voltage is applied immediately after incoming seizure.
FXS-ID Configuration ! Caution: If you use this setting when no customized signaling has been installed, all back plate LEDs turn a steady RED and normal operation of the FXS-ID voice card is interrupted. Upon request, Carrier Access will provide customized FX signaling options that can include any of the aforementioned options plus others, including answer supervision wink signaling.
FXS Voice Channel Monitoring and Testing The channel test switches on the FXS-ID back plate can be used to send a 4 second continuous ringing voltage to the tip and ring pair of each FXS voice channel. You can check the operation of an individual voice channel by attaching a test telephone to the Tip and Ring pair of a particular channel at the punchdown block or RJ-11 Harmonica, then switching ON the appropriate channel test switch to test that channel.
FXS-ID Configuration 8.7.3 “Busying Out” Individual FXS Channels Switching a channel test switch to the ON position has three results on the selected FXS channel: 1. To confirm individual channel circuit integrity, 4 seconds of ringing voltage are sent to the Tip and Ring pair. The Tip is then grounded until the channel test switch is turned to the OFF position (to the right).
FXS Voice Channel Monitoring and Testing Warning: The four-second applied ring voltage (85V) can constitute a dangerous shock hazard, and can damage attached low-impedance equipment.

Battery Reversal FXS & Dial Pulse Origination Card provides twelve 2-wire CPE analog loop-start connections to the digital T1 line using the same method used by the FXS voice card, only with the addition of Tip/Ring battery reversal. The FXS interface reverses the polarity of the battery feed towards the customer premise equipment (CPE) in response to the signaling bits coming from the T1 line.
BRFXS/DPO Applications Note: During a two-way call, the CPE -loop battery is reversed. To disconnect the call either the CPE loop current ceases or the network sends A/B bits = 0/0. The reversed state of the CPE loop, however, will be maintained until the network terminates (releases) the call. 9.

To enable this option, set Switch A on the 4-position DIP switch to ON so that cadenced ringing voltage is applied to the CPE loop during an incoming call (See Table 9-2). The battery is reversed during this time.
Self Test Loopbacks ! Danger: Four seconds of continuous ringing voltage (85 V) will be present at the Tip and Ring pair of the channel-under-test until the test telephone is picked up to trip the ringing. Requirement: A test telephone connected to the punch down block or RJ-11 Harmonica should ring for 4 seconds. 3. As an aid to network technicians troubleshooting audio problems, 4 seconds of continuous ringback tone are also sent toward the T1 network. 4.

For directions on performing Self Test loopbacks and tone transmission, enabling network loopbacks, and activating automatic Alarm Cut-Off (ACO) via the software, see the separate Remote Monitor User’s Guide. 12.3 Self Test 1 and 2 ! Caution: Because Self Test is a service-disrupting procedure. Disconnect all attached telephones prior to initiating Self Test. 12.3.
Self Test Fault Indications 2. Verify that T1 Test 1 or T1 Test 2 LED turns green after approximately 16 seconds. 12.3.2 Card Self Test At the start of the self test sequence, when the Controller asserts the self test bit toward the voice card, the following events occur on a per channel basis: • The voice card reads from the Controller and sees the self test flag at logic 1 (active). • The received A/B signaling bits are not processed since the signaling state machine is skipped in software.
12.4.3 Remote Mode: Ringback Tone or 1 Digital Milliwatt When the Access Bank II - SNMP is powered up in Remote mode, the tone sent during the Self Test can consist either of the same Ringback dual tone (440 Hz +480 Hz) sent in the Local Mode or a standard 1 kHz digital milliwatt test signal. In Remote mode, Ringback tone is the default setting. 12.
Remote Mode: Remote T1 Line or Payload Loopbacks 12.7 Remote Mode: Remote T1 Line or Payload Loopbacks In Remote mode, if the T1 line is ANSI T1.403 ESF formatted and Network Loopback detect and ESF ANSI detect both has been enabled, the two types of loopback codes the Access Bank II - SNMP can be configured to detect are Remote T1 Line and Remote Payload Loopback. The default setting in Remote mode is Remote T1 Line Loopback. 12.8 ANSI T1.

14.3 SNMP Management The Access Bank II SNMP provides: • Built-in SNMPv2 Agent software providing network statistics, information retrieval and update, trap thresholds, and automatic transmission of trap data to Network Management Stations. • Application Support for Simple Network Management Protocol (SNMP) and Telnet, per RFC 1902 through 1907. Management Information Base (MIB), per RFC 1573. • Transport Support for Transport Control Protocol (TCP) and User Datagram Protocol (UDP), per RFC 1213.
SNMP Management objects with predefined MIB data structures. The Access Bank II/SNMP uses the Bellcore® standard MIB for T1 interfaces. Manager operations include simple “get” and “set” commands to retrieve and update MIB data in the Agent. Normally, the Manager polls the Agent periodically to check traffic statistics. However, the Manager can also set thresholds for traps.
14.3.
SNMP Management • T1 interface statistics, per RFC 1406 14.3.7 Traps The Access Bank II SNMP agent supports the following standard SNMPv2 defined traps. In the future, enterprise specific traps will be added. Interpretations of the trap values are: coldStart Trap A coldStart(0) trap signifies that the sending protocol entity is reinitializing itself such that the agent's configuration or the protocol entity implementation may be altered.
14.3.8 Maintenance The Access Bank II SNMP provides maintenance functions for the following SNMPv2 operations. • Loopback operations: T1 remote line and payload. Loopback operations verify and segment operating network interface circuits. • Fault isolation: BERT QRSS test patterns in conjunction with loopback operations. The user may also employ standard Internet PING function tests to check the connectivity at the IP layer.

GLOSSARY 10Base-T: 10Base-T is an IEEE standard for operating Ethernet local area networks (LANs) on twistedpair cabling using the home run method of wiring (the same as the phone company uses) and a wiring hub that contains electronics performing similar functions to a central telephone switch. The full name for the standard is IEEE 802.3 10Base-T.
CHANNEL SERVICE UNIT: See DSU/CSU CONNECTION: A connection is a logical linkage between timeslots on a span or between spans. CROSSTALK: Crosstalk occurs when you can hear someone you did not call talking on your telephone line to another person you did not call. You may also only hear half the other conversation (i.e. just one person speaking). There are several technical causes for crosstalk relating to cable placement, shielding and transmission techniques.
DNIS (DIRECTORY NUMBER IDENTIFICATION SERVICE): DNIS is a feature of 800 and 900 lines that provides the number of the caller dialed to reach the attached computer telephony system. Using DNIS capabilities, one trunk group can be used to serve multiple applications. The DNIS number can be provided in a number of ways, inband or out-of-band, ISDN or via a separate dedicated data channel.
Access Bankô II, that incorporates a controller, channel service unit (CSU), ringing generator and power converter on a single card to interface between the T1 network and the analog functions of the channel bank. PBX (PRIVATE BRANCH EXCHANGE): PERFORMANCE REPORT MESSAGE (PRM): PLAR (PRIVATE LINE AUTOMATIC RINGDOWN): A leased voice circuit that connects two single telephone handsets together. Whenever either handset is lifted, the other instrument automatically rings.
naling. TRUNK PROCESSING (TP): WINK: A signal sent between two telecommunications devices as part of a handshaking protocol. It is a momentary interruption in SF (Single Frequency) tone, indicating that the distant Central Office (CO) is ready to receive the digits that have just been dialed. In telephone switching systems, a single supervisory pulse. On a digital connection such as a T1 circuit attached to an Access Bank II, a wink is signaled by a brief change in the A and B signaling bits.
