Installing the Remote Office 9150 unit
n
telephone cable: One end of the cable must provide a male 50-pin
connector. (This end connects to the Remote Office 9150 unit.)
Ensure the other end of the cable matches the connectors needed to connect
to the telephones or trunks. (For example, if you are using a BIX block to
establish the telephone connections, the wires inside must be exposed.)
Notes:
n
Two telephone cables are required, depending on how many telephones
and trunks are installed. (Each telephone cable provides support for up
to 16 digital telephones, and two ISDN BRI lines providing two
B-channels each. The Telco 1 cable also provides support for one analog
station such as a fax machine.)
Nortel Networks recommends that you use straight-through Amphenol
cables instead of side-entry Amphenol cables. (See "Cable attachment"
on page 116.)
n
Digital telephones should be located no further than 1230.7 meters
(4000 feet) from the Remote Office 9150 unit.
n
The analog device should be located no further than 307.7 meters
(1000 feet) from the Remote Office 9150 unit.
n
Ethernet cable
If you are connecting the Remote Office 9150 unit to a hub, you need a
standard CAT5 unshielded twisted-pair (UTP) straight-through Ethernet
cable. The cable should be no longer than 100 meters (325 feet) in length.
