4 xT1/E1 + 10/100TX over SFP-based fiber line card

Overview
The AT-CM70S T1/E1 media converter line card is
designed to increase the capacity of an existing
point-to-point fiber network, by multiplexing up to
four T1/E1 TDM channels and one Fast Ethernet
channel over a single fiber interface. By the use of
a modular fiber SFP (mini-GBIC) uplink, installers
can easily deploy the AT-CM70S over a wide range
of fiber optics, including multi-mode, single-mode
and bi-directional fiber at distances up to 40km.

Expanding the Bandwidth
Each AT-CM70S media converter card features
four T1/E1 twisted pair interfaces, and one
10/100TX copper twisted pair interface. All five
data paths are multiplexed onto a single SFPbased
fiber interface, for transportation up to
40km.A second AT-CM70S blade at the remote
site de-multiplexes the single, and provides the
five separate data streams.

Deploying the AT-CM70S allows existing installed
fiber cables, carrying only a single T1 or E1 channel,
to be upgraded to carry more than four times the
amount of traffic, without having to install any new
fiber cable. All the T1/E1 channels are fully
independent, allowing a service provider to
expand the capabilitities of an existing fiber, whilst
providing WAN services to different customers.
