TRM01-ET100

Fractional T1 to 10/100Base-TX

Ethernet Bridge Card

The TRM01-ET100 Bridge Card is a single slot card that can be installed in any available slot to provide Ethernet over T1 transmission. The bridge

engine uses an ASIC design for wire speed performance and supports industry standard HDLC encapsulation. The TRM01-ET100 bridge is an

economical solution for LAN to LAN applications over Fractional T1 transport.

●

Features

Specifications

TRM01-Data

Fractional T1 to Data Card

The high-speed data cards support in two T1 types; fractional T1 and Unframed T1 (transparent) and with data communication interfaces for

V.35, RS-530, X.21 and RS-449(V.36). All line cards come with adapter cables that terminate in the appropriate user interface for DCE. Simple

DIP Switch settings provide all the control for T1 and Dataport settings. When the TRM01 is equipped with optional SNMP, centralized manage-

ment can configure and monitor the card and performance without manual DIP setting.
