A-2ADMINISTRATION REQUIREMENTS

Line Compensation

Relates to the distance between the switch and the network channel-terminating equipment (NCTE), channel-division multiplexer (CDM), channel-expansion multiplexer (CEM), or a digital signal level 1 (DS1) cross connect field (called a DSX-1).Refer to System 75 R1V2 under ADMINISTRATION ISSUES for details on selecting the appropriate value.

NOTE: If the switch is equipped with a TN722B and if this connection is to a 4ESS configured with 4e11 generic software, then digital multiplexed interface with bit-oriented signaling (DMI-BOS), extended superframe (ESF) framing, and bipolar with 8-zero substitution (B8ZS) line coding may be selected as options.

Special access connections are always via digital 4-wire ear and mouth (E&M) tie trunks. At the 4ESS, and for MEGACOM service applications, this trunk type is called PBX (l-way outgoing trunks). At the 4ESS, these PBX trunk types are translated for DTMFWK type signaling.

NOTE: If this connection is to a 4ESS configured with 4e9 software, then rotary must be used rather than touch-tone (tone). The general assumption is that a 4ESS will be configured with 4e10 or later software.

At the 4ESS, and for MEGACOM 800 service applications, this trunk type is called PBX (1-way incoming trunks). At the 4ESS, these PBX trunk types are translated for DTMFWK type signaling. The Digits and Digits Treatment fields may or may not be translated depending on the local numbering plan and other addressing requirement or restrictions for a 4ESS toll office.
