AT-CM70S The AT-CM70S 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.
Each AT-CM70S line card features the following:
ˆ One RS-232 terminal port with an 8-pin Mini-DIN connector
Refer to “8-Pin Mini-DIN Console Port Pinouts” on page 93
ˆ One 10/100Base-TX twisted pair port with an RJ-45 connector
Refer to “10/100Base-TX Twisted Pair Ports” on page 29
ˆ One SFP expansion slots (SFP transceiver sold separately)
Refer to “SFP Expansion Slots” on page 35
ˆ Four T1/E1 ports with RJ-48 connectors
Refer to “T1/E1 Port (AT-CM70S Line Cards Only)” on page 33
