Allied Telesis 4 xT1/E1 + 10/100TX over SFP-based fiber line card network media converter

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.
