T1/E1 Switches-Telco Edgelink 810 switch, 4 Port T1 Digital Cross Connect Switch, 4 Port E1 Digital cross Connect Switch-T1 E1 Integrated Switches

American Tech Supply carries the 4 Port T1 Compact Digital Cross-Connect Switch from Telco Systems. The 4 Port E1 Digital cross connect switch from Telco Systems reduces T1 line costs by 50% or more. Telco Systems’EdgeLink 410, a compact 4-port T1 or E1 digital cross-connect switch, is ideally suited to a variety of network applications. Any time-slot can be mapped to any other time-slot for fully non-blocked circuit routing.

Compact T1/E1 Access Platform


Integrate T1/E1, V.35/RS422 access into a single compact unit! EdgeLink810 is an intelligent highspeed platform that integrates digital cross-connect switching and data port access into a compact package. Engineered for high reliability and wide operating temperature range, the EdgeLink810 is ideal for edge-ofnetwork grooming and backhaul, especially in environmentally harsh conditions. The unit occupies only one rack mounting space, which in combination with front access to all field connections, makes EdgeLink810 suitable for the smallest cell site and base station installations. EdgeLink810 is the smallest 8 port cross connect available.
Wireless network operators, Internet Service Providers (ISP’s) and carriers can deploy EdgeLink810 in a variety of applications. These include wireless base station backhaul, E911 services, subscriber location and public network interconnection over T1/E1 or highspeed data circuits. EdgeLink810 can also be used to protect T1/E1 lines for disaster recovery and alternate path solutions.
EdgeLink810 supports all transport systems and can be directly connected to leased T1/E1 lines using built-in CSU’s. Compact Size = Flexibility Two module slots provide support for 8 x T1 or E1 cross-connect switching or combinations of T1/E1 cross-connect switching and data port terminations
