32-channel P-side ports to control the LSGs. The ten 32-channel P-side ports
are on the DCC of each array.
Both the LSGs and the separate line cards in the LSGs are numbered. The LSG
numbers are in an OPM range from LSG-00 through LSG-19. Line card
numbers range from 00 through 31. The line equipment numbers (LEN)
identify and arrange the line cards in the DMS switch central control (CC). An
example of this event appears in the following table.
Table 2 Parts of LEN for OPM
Part Description
Site Four-character alphanumeric name that identifies the remote site of
the OPM. The LEN for a line configured in the host office has a site
name of HOST.
Frame Number (00-99) that identifies the OPM frame that contains the line
card.
LCM Number (0) that identifies the LCM in the frame that contains the line
card. (The OPM contains only one LCM identified as LCM-0).
LSG Number (00-19) that identifies the line subgroup of the LCM that
contains the line card.
Circuit Number (00-31) that identifies the position of the line card in the
LSG. The example below shows how line cards are numbered for
identification in any LSG.
A description of a complete LEN for an OPM line card that consists of five
units of information appears in the following table. The example shows LENs
for line cards in a normal office. The first two LEN are for OPM-supported
lines.
