Chapter 8: Configuring the T1/E1 Ports on the AT-CM70S Media Converter Line Card

Selecting the Management Method for the AT-CM70S Line Card
Unlike the other Converteon line cards, the AT-CM70S Line Card comes
with a Console port for local management without the AT-CV5M02
Management Card. You can use the Console port to configure the T1/E1
ports when the line card is installed in a chassis that doesn’t have a
management card.
During the initial configuration of the AT-CM70S Line Card, you must
specify whether you intend to configure the line card with the Console port
or the management card. This is referred to as setting the card’s UART
(universal asynchronous receiver/transmitter) setting. The card has two
settings—UART local console mode and UART backplane mode. The
UART local console mode lets you configure the card’s parameters from
the Console port on the card. This setting, the default setting, is the
appropriate setting if the AT-CM70S Line Card is installed in a chassis that
doesn’t have a management card.
If the chassis has a management card, you should change the
management method to the UART backplane mode. This settings lets you
configure the line card using the menus in the management software of
the management card. (The term “backplane” refers to the backplane in
the AT-CV5000 Chassis.)
Here are factors to consider when choosing the UART setting for this card:
ˆ Setting the UART setting requires the AT-CV5M02 Management Card.
You cannot set the UART setting from the Console port on the
AT-CM70S Line Card.
ˆ When the line card is set to the UART local console mode, you have to
use the Console port and you can only adjust the T1/E1 settings. You
cannot use the management card to change any of the settings on the
card.
ˆ When the card is set to the UART backplane mode, you can use the
management card to change all of the card’s settings, including the T1/
E1 settings.
ˆ To download new management software to the line card, the card
must be set to the UART backplane mode.
The AT-CM70S Line Card must be used in pairs, with the fiber optic port
on the SFP module in one line card connected to an identical SFP module
in another AT-CM70S Line Card. However, the local and remote cards do
not have to use the same UART settings. In fact, they’re likely to have
different settings because one of the cards will probably reside in the
AT-CV5000 Chassis with a management card and the other at a remote
site in a chassis that does not have a management card.
