. INSTALLATION
3.1 Unpacking
Remove the unit from the shipping container and examine it carefully
for external damage. If shipping damage is apparent, notify the
shipper immediately.
The following accessories are included with the unit:
•external power supply
•manual
•warranty, maintenance contract and repair information
•Modem to Composite cable (black) for connecting the unit to
an external modem or DSU/CSU
•Network Management Port cable (green) for connecting the
network management port to an asynchronous terminal or PC
for configuration
•If your unit has the optional built-in DSU/CSU, a cable is also
included for connection to the phone line.
3.2 Setup
The composite port must be configured properly for the type of link
used (Sync or Async). In addition, the data port must have the proper
speed setting. This is done using the network management port CN
and CP commands (see Section 5).
3.3 Using Leased Line Modems
In this section, a reference to modem includes modems, digital radios
or DSU/CSUs for leased line installations.
Connect the modems to the phone line and power ON the modems.
Confirm the presence of carrier at each modem. If carrier is not
detected at both ends, recheck the option settings. If carrier is still not
present, check the cable from the telephone line to the modem. If
everything is correct and still no carrier call the manufacturer of the
modem or contact the telephone company for assistance.
Connect the CAA composite port to the modem. A two foot RJ45 to DB-
25 male cable connects the composite port of the CAA (the RJ45
connector second from the left when viewed from the rear) to the data
port of the modem (usually a DB-25 female connector). See Section 6 for
cabling information.
