TDM Commands (Applicable to 7210 SAS-M when using the CES MDA)
Page 210 7210 SAS M, T, X, R6, R12, Mxp, S, Sx Interface Configuration Guide
e1
Syntax e1
Context config>port>tdm
Description Platforms Supported: 7210 SAS-M.
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.
Parameters
duration — Sets the duration for the BERT test.
Values Up to 24 hours, in seconds or hh:mm:ss format
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.
buildout
Syntax buildout short
Context config>port>tdm
Description Platforms Supported: 7210 SAS-M.
This command specifies line buildout (cable length) for physical DS-1 interfaces on the T1/E1 CES MDA.
Default short
Parameters short — Sets the line buildout for length runs up to 655 feet.
lbo
Syntax lbo [0dB | -7.5dB | -15.0dB | -22.5dB]
Context config>port>tdm
Description Platforms Supported: 7210 SAS-M.
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:
Values lboNotApplicable — Not applicable
