The Model 2345 managed T3 fiber optic modem with Optical Line Interface Module (OLIM) extends
T3 (44.736 Mbps) signals between devices located up to 120 Km apart. The OLIM supports
multimode and single mode fiber. Use the modem to extend a PBX, router, video codec, DS3
multiplexer, or ATM switch.
The 2345 transports B3ZS or AMI coded data. The 2345 supports both framed and unframed modes.
Framed mode supports C-bit Parity or M-13 framing patterns, can correct polarity errors, and gathers
DS3 statistics. Unframed mode passes data with full transparency.
The 2345 can be used in a UCS 1000 or UCS 1001 chassis or directly as a standalone.
• The UCS 1000 Chassis can hold up to 15 model 2345 modems; you can manage each 2345 either
directly through the serial port or through the Domain Management Module (DMM) within the
domain.
Note: The Chassis Interconnect Module (CIM) must be present in the UCS 1000 chassis in order
for the DMM to recognize the 2345 modules.
• The UCS 1001 Chassis can hold up to two model 2345 modems; you can manage each 2345
directly through the serial port.
• The standalone 2345 provides one modem that you can manage directly through the serial port.
The 2345 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.
The rackmount 2345 front panel, shown in Figure 1, includes:
• EIA-232, BNC, and optical connectors
• Reset switch
• LEDs for:
• System Status (STA)
• Configuration (CFG)
• Composite Loss of Signal (CLS)
• Test/Loopback (TST)
• Electrical Loss of Signal (LOS)
• Alarm/Unframed Data (AIS/UNFRMED)
The front and back panels on the standalone 2345, shown in Figure 2, include the same connectors,
switch, and LEDs, with these additional items:
• Alarm In and Out connectors
• Serial port
• MDM/TRM and Loopback switches

The 2345 supports both full modem redundancy, with two modems, and fiber redundancy, through
dual-path OLIMs. You can enable automatic or manual redundancy or disable the option.
Dual-path modules provide redundancy for the fiber link. The two transmit (Tx) outputs and two
receive (Rx) inputs are connected on different fiber. Both Tx output transmit the same data; one Rx is
active and the other is inactive. If data is lost on the active Rx, the module switches automatically to
the inactive Rx and you can troubleshoot while data transmission continues.
When the redundant mode is set to Auto and the link fails, the software logs an alarm and switches to
the secondary link. If the redundancy mode is set to Manual and the link fails, the software logs the
alarm, but does not switch to the secondary link.
For details on setting up the hardware for redundancy, see Chapter 2. For details on setting up the
software, see "Set Up Redundancy" on page 3-12.

Hardware Installation and Functions
You can install the 2345 in a UCS 1000 or 1001 or place a standalone 2345 in a flat, secure location.
Before starting to install the 2345 in a chassis, make sure the chassis is installed and its User Manual
is available for reference. If the system includes an optional DMM and CIM(s), make sure these are
available:
• Serial cable (required to connect to a VT100 type terminal or PC)
• VT100 type terminal or PC to run the User Interface Manager software
• The DMM and CIM manuals
Setup and Installation
Follow these guidelines to determine which slot(s) can hold the 2345:
• You can install the 2345 in a UCS 1000 in any slot except 0 ( reserved for the DMM and CIM) or
the power supply slot(s).
• You can install the 2345 in a UCS 1001 in either slot.
• If this is a redundant pair of 2345s, plan to install the primary modem in an odd-numbered slot
and install the secondary modem in the next higher-numbered slot, such as slots 3 (primary) and 4
(secondary) or in a UCS 1001, left (primary) and right (secondary).
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. If this is a standalone 2345, remove four screws from the back panel and slide the board part of
the way out to access the switch and jumpers.
3. Set jumpers as needed for

4. Set SW3: for Framed Data, set it toward the BNC connectors; or for Unframed data, set it away
from the BNC connectors.
5. If this is a standalone 2345, slide the board back in, being careful to align the switches in the front
panel, then replace the four screws in the back panel.
6. Slide the rackmount 2345 into the slot in the chassis or place the standalone 2345 on a flat, secure
surface, then slide the OLIM into the 2345, and tighten all captive screws.
Note: The 2345 is hot-swappable and can be inserted or removed without disrupting data transfer
in other modules in the chassis.
7. If this is a standalone 2345, see Figure 2 and connect the alarm outputs:
• At ALM OUT, on the rear panel, connect devices to receive alarm information.
• NO The contacts are open for normal operation and closed in a fault condition
• COM The electrical common
• NC The contacts are closed for normal operation and open in a fault condition
• At ALM IN, on the rear panel, connect devices to supply alarm information. Connect cabling
from the + output on the device to MAJ or MIN_IN+, from the - output to MAJ or MIN_IN-, and
from ground on the device to CH_GND on the standalone.

8. Connect the power:
• If this is a rackmount 2345, the module receives power automatically from the chassis. For
details, see the user manual for the chassis.
• If this is a standalone 2345, see Figure 2 and connect the power at the back panel:
• For AC power, plug the power cord into the socket on the 2345; to turn off power, unplug the
power cord.
• For a DC supply, loosen the screws for the GND and -48 VDC terminals, then slide the wires
under the square washers, and tighten the screws. Use an ohmmeter to verify that -48 VDC is
not shorted to GND, then connect the power cables to the power source.
The 2345 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:
9. If you will manage the 2345 directly, rather than through a DMM, plug a serial cable into the
10. To connect to T3 at the local site, follow either of these steps:
• For a non-redundant modem, plug the BNC cables from the local equipment into the Rx and
Tx connectors using Tx to Rx, and Rx to Tx orientation.
• For fully-redundant modems, use Canoga Perkins Y-cables p/n C002-000. Plug the single
end of a Y cable into Rx on the local equipment and plug each dual end into Tx on the
modems. Plug the single end of another Y cable into Tx on the local equipment and plug
each dual end into Rx the modems.
11. To connect a local pair of fully-redundant standalone modes, plug Canoga Perkins cable p/n
C001-000 into the Redundancy connectors located at the lower center of the rear panels.
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.
12. 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.
Model 2345 User Manual

EdgeAccess Universal Chassis System
13. Use canned air to blow out any dust from the female fiber coupler.
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
14. Plug in the optical cables with Tx to Rx, and Rx to Tx orientation. For redundancy, use primary
to primary and secondary to secondary orientation.
15. Label each cable and connector with the signal name and direction.
16. For cable connections to other modules in the chassis, see the appropriate user manual for details.
Canoga Perkins recommends that you determine and record link attenuation and transmission power
before starting normal link traffic. The attenuation factor and transmission power identify potential
problems with links near the lower limit of receiver limitations.
For details on link attenuation and transmission power, see Chapter 5.
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, TST, LOS, and CLS 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 LOS and CLS LEDs show the electrical and optical signal conditions. Table 3 shows the LED
states for various conditions.
