P-side communication cards
The P-side communication cards connect the SRHE to Star Modules with
DS-1 links. Up to 32 DS-1 links can connect to up to 16 Star Modules. The
NTTR87AA and NTMX81AA cards described earlier support these
connections on the P-side. One or two DS-1 links connect each Star Module
to the Star Hub. Like the C-side links, the links to the Star Hub also use
HDLC/LAPD protocol. The paragraph "Star Module to Star Hub DS-1 port
mapping" in this chapter describes the DS-1 link configuration.
