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.35
• EIA-530/Model P53 supports:
• External station Clock
• Internal Clock
• External Clock
• EIA-422A/Model T22
• EIA-422A/Model D22
• TTL/BNC
• T1/E1
• T88
Use the 2340 with the Universal Chassis System (UCS) in the UCS 1000, UCS 1001, or Model 1040
or 1050 Standalone Enclosure. The UCS 1000 will hold up to 15 modems, the UCS 1001 can hold up
to two modems, and a standalone enclosure holds one modem. Figure 1 shows the 2340 modem.

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. The optical receiver extracts the clock and
data information from the optical signal, establishes the frame-bit lock, then demultiplexes the clock,
data, control signals, and routes the signals to the interface circuits.
The 2340 operates asynchronously at up to 1.5 Mbps and synchronously at up to 2.048 Mbps.
Operation mode options include external, internal, and slave timing. The built-in clock can generate
the common clock rates, including most Nx56/Nx64K rates.

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. Appendix A provides information for Return
Material Authorization (RMA).
2. Insert the 2340 into an unused slot in the chassis. Slide the 2340 into the rails and push it firmly
into the backplane, then tighten the captive screws. If you encounter resistance, check that no
connector pins are bent.
If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300 for technical assistance.
3. Insert the ELIM into the 2340. Slide the ELIM into the rails and push it firmly into the
connector, then tighten the captive screw. If you encounter resistance, check that no connector
pins are bent.
Note: The 2340 and ELIM are hot-swappable and can be inserted or removed without disrupting
data transfer in other modules in the chassis.
The 2340 uses electrical cables to connect to the local site and fiber optic cables to connect to the
remote modem. Follow these steps to connect the electrical and optical cables:
4. If you will control the 2340 directly through the serial port, plug a DE-9 straight-through serial
cable into the EIA-232 port on the DMM and the serial port on the PC or terminal; for the pinout,
see Table 22 on page 6-2.
5. To connect to the local site, plug the electrical interface cables from the local equipment into the
Rx and Tx connectors using Tx to Rx, and Rx to Tx orientation.
Dirty optical connectors are a common source of link loss or attenuation problems, especially for
single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever there is a
significant or unexplained light loss. To prevent contamination, always install protective dust covers
on unused fiber optic connectors.
6. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free isopropyl
alcohol pad from a fiber cleaning kit.
7. Use canned air to blow out any dust from the female fiber coupler.
Model 2340 Model User Manual
2-1
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. For cable connections to other modules in the chassis, see the appropriate user manual for details.
2.2 Power Up and Front Panel Functions
During the initial power-up sequence, all LEDs light amber. When start-up is complete, the setup and
installation are correct, and data is transmitting normally across the link, the STA LED lights green
and the CFG, CLS, and TST LEDs are off. During normal operation, the LED colors change
according to system and port conditions. The STA, CFG, and TST LEDs show the module condition.
The CLS LED shows the optical signal conditions. Table 1 shows the LED states for various
conditions.

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.
3.1 L130: Configurable EIA-232/423/530/P53/449/V35
The L130 ELIM is electrically compatible with the EIA-423A, EIA-232D, and EIA-530 standards.
Table 2 lists the EIA-423/232 and EIA-530 signals with the pinouts for the female DB-25 connector
and the signals and pinouts for the adapters that support EIA 449/422 or V.35.
The control leads comply with the interface standards. RTS, CTS and DCD provide handshaking.
TD and RD are data input and output. SCT is the clock output for Internal and Slave modes. SCR is
always the clock for RD. SCTE is the clock input for External mode. DSR, DCD, and CTS output
are selectable in software.
The EIA-423 and EIA-232 interface includes these five end-to-end control leads:
• RTS to DCD
• DTR to RI
• STD to SRD
• SRTS to SDCD
• DSRS to SCTS
DSR and TM are local status leads that follow the functions described in EIA-232D. DSR typically
indicates that the modem is ready to handle transmit data. TM indicates that a loopback is active on
one or both modems. LL and RL are loopback control inputs and follow the software setting, unless a
2340 in a Model 1040 is in hardware mode and the function switch on the enclosure is set for
loopback, then LL and RL are ignored. For details on the software and loopback tests, see Sections
4.12 and 5.1.
Model 2340 Model User Manual
3-1
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.

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. The interface supports
these typical applications:
• With encryption devices on the BLACK side, where modems act as the network and supply the
synchronous clock, or on the RED (clear) side of data encryption (KG) equipment as the "tailcircuit adapter" device. This allows the modem to accept two synchronous clocks, one for
transmitting (external clock) and one for receiving (FIFO input clock, SCT becomes an input).
• With systems that communicate over geosynchronous satellites, the FIFO can make up for clock
drift (Doppler shift) caused by the satellite's elliptical orbit around the earth.
Use the External Station configuration when an external station (slave) clock provides the timing (see
Figure 2). In this application, the modems act as the network, although the timing is from an outside
source. When connecting KG or KIV encryptors on the Black side with an external timing device, go
to the Functional Configuration screen and set the interface configuration values: set the modem with
the timing source to external; set the other modem to slave; for details, see Section 4.7.

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.

circuit. When connecting KG or KIV encryptors on the Red side to a DTE device, go to the
Functional Configuration screen and set the interface configuration parameters: set the operating
mode for the modem at the Red end to External and the modem at the DTE end to Slave; for details,

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. TT provides the
transmit clock for External mode.
The control signal outputs are unbalanced drivers and the B-leads of the differential control signal
outputs are tied to signal ground to comply with EIA-422. None of the control leads interact with the
data transmission, but they do comply with DTE interface requirements. Most of the control leads are
end-to-end signal channels that can conform to EIA-449 interface standards.
The EIA-449 interface includes three end-to-end control leads; input to output:
• RS to RR
• TR to IC
• NS to SQ
DM and TM provide local status and follow the RS-449 functions. DM typically indicates that the
modem is ready to receive data. LL and RL are loopback control inputs and follow the software
setting, unless a 2340 in a Model 1040 is in hardware mode and the function switch on the enclosure
is set for loopback, then LL and RL are ignored. For details on the software and loopback tests, see
Sections 4.12 and 5.1.

3.9 Operating Modes and Transmit/Receive Timing
The 2340 operates in a variety of modes that support different sources of the timing signals; you can
set these on the Functional Configuration screen. For details on the Functional Configuration screen
and configuring the parameters for various interfaces, see Section 4.7.
The TD Timing signal is the clock that sends data to the fiber interface. It can be either the SCT or
SCTE signals. Use SCT Inverted to allow for data delays in relation to the clock and prevent bit
errors. Use SCTE Sampled if the clock is gapped.
The RD Timing signal is the clock that shifts data from the modem to the electrical interface. It can
be either the SCT or SCR signals.

• 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.

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.
4.1 VT100 Terminal Emulation
Connect the VT100 terminal emulation session to the DMM used in the UCS 1000 chassis or directly
to a Model 1040 enclosure.
For details on the DMM, see the Model 1500 Domain Management Module User Manual.
Setting up the VT100 session depends on which connection, serial port or Ethernet, you have
available for access to the VT100 management program. Canoga Perkins suggests that you use
HyperTerminal for your first session. For details, see the User Manual for your DMM.
Note: You must set up TCP/IP for the DMM before you can use Telnet; for details, see the manual
for the DMM.

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. See Figures 24
and 25.
Figure 24. Local Loopback
Figure 25. Remote Loopback
5.2 Optical Power and BERT Tests
To optically test the modem, cables, and connectors, follow these steps:
1. Verify the optical cable loss:
a. Clean the connectors on the fiber optic test cable before plugging it in to the Tx connector on
the 2340.
b. Warm up each component for at least 30 minutes.
c. Set the optical power meter to the proper wavelength.
d. Wait two or three minutes for the power reading to stabilize, and then read the output power.
e. Subtract out the test cable loss, then record the power level and compare it to the value on the
performance sheet for that particular 2340. Measurement tolerance is +/- 0.5 dBm.
Note: When referencing optical power levels with numerical values less than zero, the reading
closer to zero is the greater value; for example, -17 dBm is greater than -20 dBm.
5-2
Model 2340 Model User Manual
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. At the local site, connect the fiber link cable to Tx on the 2340.
h. At the remote site, set the optical power meter to the proper wavelength and connect it to the
fiber link cable.
i. Record the optical power level and compare it with the sensitivity level listed on the data
sheet for the link fiber type.
j. Subtract the remote power level from the value for the transmitter output power at the local
site. The result provides the link loss, in dB. This power level must not exceed the limit for
Rx sensitivity listed on the data sheet for the remote unit.
Note: If you cannot determine the Rx sensitivity, contact Canoga Perkins Technical Support
Department for assistance.
k. Repeat this process at the other site.
2. If the cable loss exceeds the loss budget for the modem, either a cable or a connector is faulty. If
the cable loss is within specification, follow these steps to run the loopback test; for details, see
Section 4.12:
a. At the Diagnostics screen, set the near-end modem to Remote Loopback.
b. Set the BERT tester for the clocking, data rate, and format used for the circuit; use the
existing interface cables if possible.
c. Connect the BERT tester in place of the near-end device and run the BERT test.
3. If the remote loopback and BERT tests pass, optically loop back each modem and repeat the
BERT test. If the test fails, the modem is faulty.
4. If the optical loop back and BERT tests pass, set Local loopback on each modem and repeat the
BERT test. If the test fails, the modem is faulty.
5.3 Fiber Optic Diagnostics
If the Loopback Test passes, but the modems still fail, make these checks:
• Check that the fiber optic cables are connected in the standard Tx to Rx and Rx to Tx scheme and
labeled near each end with the signal direction, source, and destination.
• Check that the data rate is set correctly.
• Check that the operating mode (internal/external/slave) is set for synchronous transmission or that
the circuit is set for asynchronous transmission.
If the problem persists, contact Canoga Perkins Technical Support.
