Overview
The AT-CM70S, see below, is a 10/100 Mbps Ethernet copper-to-fiber media
converter line card with Time Division Multiplexing (TDM) (T1/E1) transport, in
addition to regular Ethernet traffic along with OAM link management
capability. This line card offers support for 1.544 Mbps (T1) and 2.048 Mbps
(E1) services - with complete synchronization for toll-quality transport of
voice, video, and data. It also accommodates traditional testing equipment
currently used on SONET/SDH equipment for testing T1/E1 services.
The AT-CM70S line card can be installed in the Converteon™ Media
Converter chassis, either the AT-CV5000 or the AT-CV1200. The line card
features one small form-factor pluggable (SFP) transceiver slot, one copper
twisted pair port, four T1/E1 ports, and one console (Mini-DIN) port. The SFP
slot can accommodate one SFP transceiver that operates at a fixed operating
speed of 100 megabits per second (Mbps). The twisted pair port has an RJ-45
connector with a maximum operating distance of 100 meters (328 feet) and
operates at a speed of 10 or 100 Mbps. The line card is hot-swappable into
and out of the chassis.

Note
If an AT-CM70S line card is used in an AT-CV5000 chassis, it can be
managed either from its local console port or from the console port on the
AT-CV5M01 CPM module. However, if it is used in an AT-CV1200
chassis, it can only be managed from its local console port, as there is no
room for an AT-CV5M01 CPM module.
