INTRODUCTION
Token Ring Connectivity
In addition to backplane Ethernet connectivity, the ETWMIM
provides Token Ring access through the Flexible Network Bus (FNB).
Wide Area Network Connectivity
The ETWMIM allows for Wide Area Network (WAN) connection in one
of two ways — the SYNC serial port or the optional T1-SRM module.
The SYNChronous port provides connection to external WAN
equipment (e.g., a T1 multiplexer or DDS CSU/DSU). This port
supports three interface types: RS-232, V.35, and RS-449/RS-422.
The T1-SRM, an optional internal T1 CSU/DSU interface, provides an
RJ48C connector on the front panel for T1 line access. This internal T1
module meets AT&T 62411 standard requirements. See Chapter 5,
Local Management, for Configuration instructions.
