Maintenance state indicators

The Intelligent Peripheral Equipment (IPE) is a single-unit, single-shelf
peripheral node. A maximum of four single-unit IPEs are housed in one IPE
column (IPEC). The four IPEs in the IPEC are numbered from bottom to top
with ascending numerical values 0 through 3 assigned to each shelf.
As with Line Concentrating Modules (LCMs) and Digital Line Modules
(DLMs), IPEs are assigned site names to fully identify them. The assignment
of site names is controlled by entries in the SITE Table. Refer to Commercial
Systems Customer Data Schema or Defense Switched Network Customer Data
Schema for detailed information.
Each IPEC is identified by a discrimination number in the range 0 through 127.
This number plus the shelf number of the IPE in the IPEC (0 through 3) are the
parameters used with the POST command. The site name, with the IPEC
number and shelf number, are also the key to the new IPE inventory table
IPEINV.
An IPE has a maximum of six DS30A C-side links to its controlling Line
Trunk Controller (LTC), Remote Cluster Controller (RCC), Remote Cluster
Controller 2 (RCC2), and Line Group Controller (LGC). C-side links are
numbered in the range 0 through 5. At the associated Extended Peripheral
Module (XPM), where these links are P-side, the links are identified using the
range 0 through 19, covering all 20 links to a number of peripherals or trunks.
