C-side communication cards
The C-side communication cards connect the SRHE to the host LTC+, LGC+,
or RCC2 with DS-1 links.
NTTR87AA (quad frame carrier card) The NTTR87AA provides a DS-1
interface between the LTC+, LGC+, or RCC2 and the Star Hub. The
NTTR87AA is a normal-sized circuit card that contains four slots in its
faceplate. Smaller-sized circuit cards, known as dual DS-1 packlets
(NTMX81AA) are inserted into these slots to supply the NTTR87AA with its
operating identity. Each NTTR87AA holds a maximum of four dual DS-1
(NTMX81AA) packlets. Each packlet has two ports for a total of eight ports
for each NTTR87AA card.
When no NTMX81AA is required, an NTMX83AA a blank filler card is
required for open slots.
