Chapter 1
Overview
The 2346 Managed T3 Fiber Optic Modem converts and extends T3/DS3 signals between devices
located up to 100 Km apart. Use the modem to extend a PBX, router, video codec, M13 multiplexer,
or ATM switch. The 2346 receives and transmits 44.736 Mbps data on single mode or multimode
fiber optic cable.
The 2346 front panel, shown in Figure 1, includes:
•Electrical and optical connectors
•Reset switch
•LEDs for:
•System status
•Configuration
•Electrical signal
•Optical signal
Figure 1. The 2346 Front Panel
The 2346 can be used in a variety of chassis. To install a 2346 in a UCS 1000 or UCS 1001 chassis,
you must use a Model 1230 Bus Access Module (BAM); however, you can install a 2346 directly in a
UCS 1002 or standalone enclosure.
•The UCS 1000 Chassis can hold up to 15 model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of 30 2346 modems per UCS 1000.
•The UCS 1001 Chassis can hold up to two model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of four 2346 modems per UCS 1001.
•The UCS 1002 Chassis directly hosts up to fourteen 2346 modems, or thirteen 2346 modems with
the optional Domain Management Module (DMM) installed.
•Each standalone enclosure, such as a Model 1020 or 1030E, holds one 2346 modem.
The 2346 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.

Hardware Installation and Functions
Before setting up the 2346, make sure the chassis or enclosure 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
Set Up and Installation
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).
1. Before inserting the 2346, check the front panel to verify that the 2346 provides the wavelength
that matches its link partner; see Figure 1.
2. Set SW2-1 and 2-2; see Figure 2.
•SW2-1, Line Buildout (LBO): Off (default) for Short LBO, <225 ft (68 m), or On for Long
LBO, >225 ft; when software control is enabled at the Functional Configuration screen,
SW2-1 is ignored.
•SW2-2, Software override: Off (default) is software, On is hardware; set to Hardware in
unmanaged environment, only. For installation in a managed environment where you plan to
use software control (see page 3-11), set SW 2-2 to Off.
Note: If the 2346 was previously installed in a managed environment and set in the User Interface
to software control, follow these steps to set it to hardware control when installing it in an
unmanaged environment:
a. Set SW2-2 to On.
b. Insert the 2346 in a slot with the power on, then remove it.
c. Set SW2-2 to Off.
d. Insert the 2346 in a slot with the power on, then remove it.
e. Set SW2-2 as needed.

4. To install a 2346 in a UCS 1000 or 1001 chassis, you must use a Model 1230 BAM; each BAM
can hold up to two 2346 modems. Follow these steps to install the BAM and the 2346:
a. Insert a BAM into an available slot in a UCS 1000 or 1001. Slide the BAM 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.
b. Insert a 2346 into an unused slot in the BAM. Slide the 2346 into the rails and push it firmly
into the backplane, then tighten the captive screw. If you encounter resistance, check that no
connector pins are bent.
5. To install a 2346 directly in a UCS 1002 or standalone enclosure, insert the 2346 into an unused
slot. Slide the 2346 into the rails and push it firmly into the backplane, then tighten the captive
screw. If you encounter resistance, check that no connector pins are bent.
If you encounter more difficulty, contact Canoga Perkins at [phone] for technical assistance.
Note: The BAM and 2346 are hot-swappable and can be inserted or removed without disrupting
data transfer in other application modules.
6. If the 2346 is in a standalone enclosure, set the switch on the enclosure for loopback to Normal.
The 2346 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:
7. To connect to the local site, plug the BNC 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.
8. 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.
9. Use canned air to blow out any dust from the female fiber coupler.

EdgeAccess Universal Chassis System
2346 T3 Modem 2-3
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
10. Plug in the optical cables:
•If you have a simplex optical connector, use a single strand, single mode fiber cable between
a pair of 2346 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.
11. Label each cable and connector with a signal name and direction.
12. For cable connections to other modules in the chassis, see the appropriate user manual for details.
13. Measure and record fiber link attenuation and transmission power before starting normal link
traffic in order to identify potential problems with links near the lower limit of receiver
limitations. For details on link attenuation and transmission power, see Chapter 4.
Power Up and Front Panel Functions
During the initial power-up sequence, all LEDs light amber. When start-up is complete 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 and CFG/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.

Alarm Functions
The 2346 can generate Major and Minor Alarms.
•UCS 1000 and 1001: a BAM is required and holds up to two 2346 modems. On the BAM, the
Status (STA) LED lights green if either 2346 is operating normally. If both modems have errors,
the BAM STA LED lights amber.
•UCS 1001: the alarm outputs are forwarded to the chassis motherboard.
•UCS 1000 and 1002: the alarms are forwarded over the backplane to the CIM and appear on the
Major (MAJ) and Minor (MIN) CIM LEDs and then are forwarded to the DMM for monitoring
and transfer to the Network Manager as traps.
•Model 1020 enclosure: the alarm information is forwarded to the management session.
•Model 1030 enclosure: alarms are not supported.
For details about setting up the Alarms, see Chapter 3; for viewing the Alarm Log, see Chapter 4.

Software Management
You can manage the 2346 through VT100 Terminal Emulation, which is accessible by a Telnet
session, HyperTerminal or similar terminal emulation software, a standard SNMP network manager,
and CanogaView. If the 2346 is in UCS 1000 or 1002 with a CIM within a domain that includes a
DMM, you can access the 2346 through the DMM. If the 2346 is a standalone or in a UCS 1001, you
must access the 2346 directly through the serial port for the enclosure or BAM.
Setting Up for Network Management
Typically, the 2346 runs within the network on an Ethernet connection, communicating with your
Network Management Platform.
Set Up the Network Management Platform
You must run several Management Information Bases (MIBs) on your Network Management
Platform in order to successfully manage this module. Before you start, check that Standard MIB (the
industry-standard mib) is loaded. In addition, download Cp.mib, a private mib that supports all
Canoga Perkins products, available from the Canoga Perkins web site. Go to www.Canoga.com,
click Support, then click Software Download, and follow the prompts on screen.
Set Up the PC for Terminal Operation
Connect the VT100 terminal emulation session to the DMM or directly to a 2346, either standalone or
in a UCS chassis. 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.
You must set up TCP/IP for the DMM or directly-managed 2346 before you can use Telnet; for
details, see the manual for the DMM or go to page 3-7.
Note: For details on the DMM, see the Model 1500 Domain Management Module User Manual (for
UCS 1000) or the Model 1502 Domain Management Module User Manual (for UCS 1002).
These steps briefly describe how to set up your PC for a terminal connection. For details on using
Windows, see your Windows documentation.

Because the DMM defaults to VT100 mode when booting, you cannot see the screens and commands
used to switch to SLIP or PPP mode when you exit VT100 mode. Use a script file to successfully
exit VT100 mode and switch to SLIP or PPP.
1. To create a script on your PC, open Notepad and type the steps you would follow to enter SLIP or
PPP mode. On the last line, press <Space> once to select SLIP mode or twice for PPP mode
proc main
waitfor "Password :"
transmit $PASSWORD, raw
transmit "^M"
transmit "1^M"
transmit "5^M"
transmit "11^M"
transmit " ^M"
endproc
2. Save the Notepad document with a .SCP file extension in the folder where the Dialup Connection
application looks for scripts. The script will be available in the Dialup script menu. This file is
typically in the Windows\System32\ras\ folder.
3. To run the script, reach the Phonebook Entry dropdown menu and select either the PPP or the
SLIP script.
If you do not have a script file, you dial in through a modem, and the networking option is set to
VT100 operation, you will not see the screens, but the 2346 responds to the commands normally.
Follow these steps:
1. Dial in through a modem, then type your user name and password and press <Enter>.
2. Type 1and press <Enter>.
3. Type 5and press <Enter>.
4. Type 11 and press <Enter>.
5. Press <Space> once for SLIP mode or twice for PPP mode, then press <Enter> to confirm the
port choice.
The 2346 is ready to run TCP/IP applications.
