EdgeAccess® Universal Chassis System Chapter 1 Overview The Model 2340 universal fiber optic modem provides full-duplex operation at speeds up to 2.048 Mbps and distances up to 120 Km, depending on the rate and mode selections. The 2340 operates with these electrical line interface modules (ELIM): • • • • • • • • • • EIA-530 and EIA-530-A EIA-423A and EIA-232D EIA 449 and EIA-422 CCITT V.
Figure 1. Model 2340 Modem 1.1 Modem Operation The electrical connection between the network equipment and the 2340 differs according to the electrical line interface module (ELIM). The conversion between electrical and optical signals is similar in all applications. The modem multiplexes the clock, data, and control lead inputs from the ELIM, then adds framing and supervisory information.
EdgeAccess® Universal Chassis System 1.2 Fiber Optic Options The 2340 includes one fiber-optic transmitter and receiver. Use the 2340 with multimode or single mode fiber optic cable and SC or ST connectors, depending on the transmitter option. The transmitter options include: • • • Single Mode, at 1310 nm and 1550 nm Multimode, at 1310 nm CWDM For descriptions of the options by model number, see Chapter 6. 1.

EdgeAccess® Universal Chassis System Chapter 2 Installation and Setup The 2340 can be installed in a UCS 1000, UCS 1001, or Model 1040 or 1050 enclosure. For details on the chassis, see the manual for the chassis. The process to install a 2340 is the same for all chassis options. 2.1 Installation Follow these steps to install the 2340 and ELIM: 1. Unpack and inspect all components. Save the shipping carton and packing materials in case you need to return the equipment to the manufacturer.
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when installing or removing cables. 8. Plug in the optical cables: • • If you have a simplex optical connector, use a single strand, single mode fiber cable between a pair of 2340 modems, one at 1310 nm wavelength and the other at 1550 nm wavelength. If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation. 9. Label each cable and connector with a signal name and direction. 10.
EdgeAccess® Universal Chassis System Chapter 3 Electrical Data Interfaces The 2340 supports these ELIMs: • • • • • • • • • • • L130 Configurable EIA-232/423/530/P53/449/V35 P53 Interface for the L130 L131 EIA-422 DC-37 with controls L132 EIA-422 TwinAx L133 TTL BNC L134 T1 RJ-45 L135 T1 DA-15 L136 E1 RJ-45 L137 E1 DA-15 L138 EIA-422 DC-37 without controls L139 T88 In addition, this chapter describes operating and clock modes for the ELIMs. 3.
The V.35 interface signals follow the EIA-423 and EIA-232 protocols with minor changes, including these three end-to-end control leads: • • RTS to DCD DTR to RI DSR indicates that the modem is ready to receive data. TM is On only when loopback is active on either or both modems. Table 2. Signals and Pinouts: EIA-423/232, -530 Protocols and EIA-449/42 and V.35 Adapters Signal Name Path Frame Ground EIADB-25 EIA-530 DB-25 EIA- DC-37 CCITT V.
EdgeAccess® Universal Chassis System 3.2 P53 Interface for the L130 The L130 ELIM supports the P53 interface and external DCE/DTE adapter that converts the interface to DTE with male DB-25 connector This interface supports FIFO buffers for received or transmitted data and a programmable delay line to fine-tune the clock and data timing.
Use the Internal configuration when the network equipment is set for Internal Timing (see Figure 3). In this application, the modems act as the network timing source. When connecting KG or KIV encryptors on the Black side, go to the Functional Configuration screen and set the interface configuration parameters: set the operating mode to Internal, then set the Internal Rate, then set the delay time; for details, see Section 4.7.
EdgeAccess® Universal Chassis System 3.3 L131: EIA-422, DC-37 With Control Signals The L131 ELIM for EIA-449 is electrically compatible with the EIA-422 specifications for clock and data and with EIA-423 for control signals. It uses a female DC-37 connector; Table 3 lists the pinout. SD, RD, ST, RT and TT provide the primary data and clock signals. ST provides the transmit clock reference for Internal and Slave modes. RT provides the clock for the received data.

It uses five TwinAx connectors. Table 4 lists the supported signals. Table 4.
EdgeAccess® Universal Chassis System 3.6 L134, L135, L136, L137: T1 and E1 The L134, L135, L136, and L137 ELIMs are electrically compatible with T1 or E1 specifications. Tables 6 and 7 show the connector pinouts. • L134 supports T1 and transmits AMI or B8ZS code. The ELIM includes an RJ-45 connector; use a 100 ohm twisted pair cable to connect to the local network equipment. L135 supports T1 and transmits AMI or B8ZS code.
3.7 L138: EIA-422, DC-37 Without Control Signals The L138 ELIM is electrically compatible with the EIA-422A specifications. It includes a female DC-37 connector, but not the control signals available with the EIA-449 interface. Table 9 lists the supported clock and data signals. Table 9.
EdgeAccess® Universal Chassis System • External mode: Use when the DTE provides the clock or when the 2340 is used as a tail circuit connecting to a DCE. The other device sends this clock to the modem as the TD Timing signal. Go to the Functional Configuration screen and set the interface configuration values: select External mode, then set the TD Timing source to SCTE or SCTE Sampled for a gapped clock. See Figure 5.
• Slave mode: This 2340 uses the clock from the remote modem as both the TD Timing and RD Timing signals. Go to the Functional Configuration screen and set the interface configuration values: set the interface type, then select Slave mode, then set the TD Timing source to SCT for most applications or to SCTE, SCTE Sampled, or SCT Inverted for high data rates or a long cable to the DTE. See Figure 7.
EdgeAccess® Universal Chassis System Chapter 4 Software Management If the 2340 is in a Model 1040 enclosure or is in a UCS 1000 chassis within a system that includes a DMM and a CIM, you can manage the 2340 through VT100 Terminal Emulation, which is accessible by a Telnet session, HyperTerminal or similar terminal emulation software, a standard SNMP network manager, and CanogaView. 4.
4.3 Management User Interface The Management User Interface for the 2340 provides screens for setup, monitoring, and diagnostics. These sections discuss the screens for the 2340, using a Telnet session for access. 4.3.1 General Screen Format A typical screen, shown in Figure 8, includes standard descriptions and reference designations. Use this and other screens to configure the system, set operational parameters, and verify the system status. All screens use a common method for navigation.

EdgeAccess® Universal Chassis System Chapter 5 Troubleshooting Use the diagnostic procedures in this section to test and troubleshoot the 2340. Before starting the diagnostics, obtain this equipment: • • • • Multimeter Fiber Optic Power Meter Short (1 m or less) fiber optic jumper cable Bit Error Rate Tester (BERT) Table 21 lists troubleshooting strategies for various symptoms. Table 21.
5.1 Loopback Tests Use loopback to diagnose a fault on the optical link, either on a modem or with a cable. The 2340 supports both local and remote loopback. Local loopback loops the data internally; remote loopback loops the data at the remote modem. Set loopback either in software at the Diagnostics screen for a managed 2340 or, if the Loopback control Mode on the Diagnostics screen is set to Hardware, at the F1/NRM/F2 (Local/Normal/Remote loopback) switch on a Model 1040 enclosure.
EdgeAccess® Universal Chassis System f. If the reading is incorrect, repeat the measurement with a different test cable. If the power level is still not within range, call Technical Support. If you know the link attenuation, subtract that value from the 2340 Tx output value to determine the power expected at the remote cable end, which is the input power at the remote receiver, and skip this section. Otherwise, continue these steps to use the 2340 to measure the link attenuation. g.
