COMSPHERE 3000 Series Carrier
Depending on your configuration, use one of the following schemes for the Models 3151 and 3161 network interface (Figure 3-33).
•The 50-pin cable can be attached to a
66A-punchdown block. With this scheme, the circuits must be hard-wired to the block.
•The 50-pin cable can be plugged into a
3100-F1-930 adapter cable. This adapter cable provides 8 non-keyed modular plugs using Pins 1, 2, 4, and 5. These connect the T1 CSU or T1 DSU/CSU to a standard DDS network interface (RJ48C) and provide the new JM8-style leased-line connection for the T1 interface.
To install the Models 3151 and 3161 network interface:
.Procedure
1.Connect the network cable to the carrier.
2.If you are using the Telco connector cable, install the black plastic network cable retainer. If you are using a straight-in connector, use a small screwdriver to engage and tighten the screws.
3.Connect the individual cables with 8-pin modular plugs into the adapter for each T1 line.
