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