BRIM-WT1 OVERVIEW

The BRIM-WT1 is an optional feature for the MicroMMAC. It allows
remote connectivity of the MicroMMAC using WAN services such as T1,
Fractional T1, and Digital Data System (DDS). The BRIM-WT1 extends
the functionality of the MicroMMAC to include remote bridging and
routing capability. With the BRIM-WT1, the MicroMMAC is a remote
office workgroup hub providing up to 130 LAN ports of connectivity.

1.4

BRIM-WT1 FEATURES

WAN Connectivity

The BRIM-WT1 is equipped with a Synchronous (SYNC) serial port and
a T1/Fractional-T1 (T1/FT1) port.

The SYNC port provides a synchronous serial connection to external
WAN equipment (e.g., a T1 multiplexer or DDS). This port supports the
following interfaces:

•

RS232 (9.6 Kbps - 19.2 Kbps)

•

RS422/RS449 (9.6 Kbps - 2.048 Mbps)

•

RS530 (9.6 Kbps - 2.048 Mbps)

•

X.21 (9.6 Kbps - 2.048 Mbps)

•

V.35 (9.6 Kbps - 2.048 Mbps)
