DS1 tie trunk example

Digital Signal Level 1 (DS1) tie trunks provide a 1.544 Mbps (T1) or 2.048 Mbps (E1) digital data service between two collocated configurations or between the configuration and a data network.

See these examples:

Collocated DS1 interface trunks

Two TN464HP DS1 Interface circuit packs can be in collocated configurations. A DS1 Interface circuit pack in one configuration can be connected to a DS1 in another configuration. A C6D cable can be used if the distance is less than 50 feet (15.2 meters). If the distance is between 50 feet (15 meters) and 1,310 feet (399 meters), use a C6E cable.

Note:

The maximum distance between cabinets is 1,310 feet (399 meters).
