ASMi-52L Installation and Operation Manual Chapter 1 Introduction
Overview 1-5
All tests can be activated from the local unit or from the remote unit.
Real time alarms provide information on the system status, indicating management
failure, synchronization loss, and other conditions.
Statistic Collection
ASMi-52L supports SHDSL statistics collection.
SHDSL Repeaters
Up to eight SHDSL repeaters can be installed in line to increase the operation
range of the modem. ASMi-52L provides basic management of the repeaters.
Control Port Characteristics
ASMi-52L includes a V.24 (RS-232) asynchronous DCE port, designated
CONTROL and terminated in a 9-pin D-type female connector. The control port
continuously monitors the incoming data stream and immediately responds to any
input string received through this port.
The terminal can be connected either directly to the ASMi-52L control port, or
through a modem or any other type of full-duplex data link. The ASMi-52L control
port interface type must be set in accordance with the connection method, as
follows:
• DCE – direct connection to terminals. Since terminals usually have DTE
interfaces, the connection to the port is made by means of a straight-through
cable.
• DTE – connection through a modem or data link. In this case, you need a cross
cable (also called a null modem cable) to connect to the CONTROL
connector.
The ASMi-52L control port can be configured to communicate at the following 57
or 115.2 kbps..6 rates: 9.6, 19.2, 38.4,
