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 on page 78
●DS1 interface trunks using T1 channel service unit on page 79 For cable descriptions, see
●DS1 cables on page 80
●Pinout of C6F cable on page 80
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).
