Installation and Operation Manual Chapter 1 Introduction

ASMi-52 Ver. 2.8 Overview 1-5

The typical ranges are based on error-free lab tests without noise.

ASMi-52CD/4W operates at data rates up to 4608 kbps, depending on internal or

external clock.

DTE Interface

ASMi-52 supports the following DTE interfaces:

• X.21

• V.35

• RS-530

• E1, as per G.704

• T1

• Ethernet/Fast Ethernet bridge with VLAN support (combined with

management LAN port).

When ASMi-52 is ordered only with the 10/100BaseT port, it can be used to

transfer user and management data.

An unbalanced E1 interface is provided via an adapter cable (CBL-RJ-45/2BNC/E1).

The impedance conversion (120Ω to 75Ω) is performed by ASMi-52 automatically

when the adapter cable connection is detected.

ASMi-52 supports multiple data rates between the range of 64 kbps and

4608 kbps. The data rate depends on the following factors:

• Unit rate mode (regular or low speed)

• Line interface type (2-wire or 4-wire)

• DTE interface type of the local and remote units (serial or E1/T1)

• Clock mode (internal or external)

• Single or multiplexed.
