RAD Data comm ASMi-52 manual DTE Interface

Installation and Operation Manual Chapter 1 Introduction

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)

•IR-IP (IP router).

When ASMi-52 is ordered only with the 10/100BaseT port, it can be used to transfer user and management data.

Note 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.

Table 1-2and Table 1-3detail the ASMi-52 data rates with the possible combinations of rate mode types, line/DTE interface types, and clock modes.
