to ITU-T or EIA standards. Equipment using networks interfaces
other than switched-56 (four-wire 56 kbps) must conform to the
following requirements:
The appropriate mechanical and electrical network interface
must be present.
All clocking signals must be generated by the equipment
(driven by the network).
To use the Switched-56 network interface, the Switched-56 networks
must conform to the following standards:
AT&T Technical Reference: ACCUNET switched-56 Service to
Public Switched Digital Service-Interface Advisory (TR 61330)
AT&T Technical Reference: Special Access Connections to the AT&T
