Equipment Abstract
Defines the interface between the telecommunications network and the customer installation in terms of their interaction and electrical characteristics. It allows the transmission of POTS and V-series data services simultaneously with a digital channel over a single mixed gauge twisted metallic pair. The procedures to operate in a TCM-ISDN noise environment are also defined. Procedures allowing the provisioning without the need for "splitters", typically installed at the ingress to the customer premises are also included, and power management procedures and link states are specified to achieve power savings at the central office and customer premises.
