Token Ring Utp Interface; Serial Interfaces - Nortel 114200-E Installation And Operating

Token Ring UTP Interface

The token ring UTP interface provides unshielded twisted-pair support. The ARN
token ring expansion module and token ring/tri-serial expansion modules contain
this receptacle.

Serial Interfaces

The ARN supports up to five serial interfaces. You can connect up to three, 44-pin
(DB-44) serial cables to an ARN that contains an optional Ethernet/tri-serial,
token ring/tri-serial, or tri-serial expansion module. You can connect one, 44-pin
serial cable to each serial adapter module (the ARN can support two).
The serial interfaces provide multiprotocol WAN connection, each operating
independently with RS-232, RS-422, RS-530, V.35, V.28, and X.21 electrical
interfaces at transmission rates from 1200 b/s to 2.048 Mb/s. When used with
standard keyed cables, the ports automatically configure to the desired electrical
interface.
You can use the following cables, described in the Cable Guide:
