Alcatel-Lucent 7210 SAS M Interface Configuration Manual page 188

Description
This command enables the context to configure E-1 parameters on a T1/E1 CES MDA. E-1 is a basic time
division multiplexing scheme used to carry digital circuits. It is also a standard WAN digital communication
format designed to operate over copper facilities at a rate of 2.048 Mbps.
If the channel has been configured for E1 on a T1/E1 CES MDA, all ports on that card can be configured for
E1. A combination of DS1 and E1 channels cannot exist on the same card.
The no form of this command disables E-1 capabilities.
duration — Sets the duration for the BERT test.
Parameters
Values
2e15 — Sends a pseudo-random 2^15 -1 pattern.
2e20 — Sends a pseudo-random 2^20 -1 pattern.
2e23 — Sends a pseudo-random 2^23 -1 pattern.

Context config>port>tdm
Description This command applies only to a DS-1 port configured with a 'short' buildout (see the buildout command).
Specify the number of decibels the transmission signal decreases over the line.
For 'short' buildout the following values are valid:
