ERM01-E1U/ET100

Unframed E1 to 10/100Base-TX

Ethernet Bridge Card

The ERM01-E1U/ET100 Bridge Card is a single slot card that can be installed in any available slot to provide Ethernet over E1

transmission. The bridge engine uses an ASIC design for wire speed performance and supports industry standard HDLC encapsula-

tion. The ERM01-E1U-ET100 bridge is an economical solution for LAN to LAN applications over an Unframed E1 transport.

●

Features

High performance bridge for 10Base-T or 100Base-TX Ethernet

extension.

Auto-MDI/MDIX detects and corrects crossed cable.

Ethernet LAN Interface on RJ-45 connector.

Transparent half / Full duplex support on WAN / LAN interface.

Automatic LAN table learning and aging.

ERM01-E1U/Data

Unframed E1 to Data Card

The high-speed data cards are available in two E1 types; one for fractional E1 and one for Unframed E1 (transparent) and with data commu-

nication 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 E1 and Dataport settings. When the ERM01 is equipped with optional

SNMP, centralized management can configure and monitor the card and performance without manual DIP setting.
