1-12 Maintenance overview

The LSGs and each line card in the LSGs have numbers. The LSG numbers

in an OPAC range from LSG-00 through LSG-19. Line card numbers range

from 00 through 31.

The system uses these numbers to identify and inventory each line card in

the DMS-100 switch by line equipment number (LEN).

Parts of LEN for OPAC

A complete LEN for an OPAC line card consists of five units of information,

as the following table describes. The LENs for line cards in a normal office

appear in the following table. The two LENs that appear are for

OPAC-supported lines.

Example LENs for line cards

Line cards are available in several types. The OPAC can support different

types of analog or digital telephone equipment.

The OPAC supports the following line cards:

297-8211-550 Standard 05.01 August 1999

Four-character alphanumeric name that identifies the remote site

of the OPAC. The LEN for a line configured in the host office has

a site name of HOST.

Numbers 00–99 identify the OPAC frame that contains the line

Number 0 identifies the LCM in the frame that contains the line

card. The OPAC contains one LCM. This LCM is LCM-0.

Numbers 00–19 identify the line subgroup of the LCM that

contains the line card.

Numbers 00–31 identify the position of the line card in the LSG.

The following figure shows the numbering of line cards for

identification in an LSG.
