50 System description
RS-232 maintenance port
The ITG-Pentium 24-port card has a DIN-8 (RS-232) maintenance port
(DCE) connection on the faceplate and an alternative connection to the
same serial port on the I/O backplane. Do not connect two maintenance
terminals to both the faceplate and I/O panel serial maintenance port
connections at the same time.
Ethernet TLAN network interface
The faceplate Ethernet TLAN network interface is a 9-pin, sub-miniature
D-type connector. The Ethernet TLAN network interface on the
daughterboard is identified as "lnPci1" in the ITG shell.
WARNING
Do not connect a TLAN cable to the faceplate 9-pin Ethernet TLAN
network interface NWK. Connect the TLAN cable to the I/O cable.
Backplane interfaces
The following interfaces are provided on the backplane connector:
DS-30X voice/signaling
This carries PCM voice and propr ietary signaling on the IPE backplane
between the IP trunk card and the Intelligent Peripheral Equipment
Controller (XPEC).
Card LAN
This carries card polling and initialization messages on the IPE backplane
between the IP trunk card and the Intelligent Peripheral Equipment
Controller (XPEC).
RS-232 serial maintenance port
This provides an alternative connection to the serial maintenance port
that exists on the I/O backplane. Use the NTCW84KA or NTMF94EA I/O
panel breakout cable to access the port. A DIN-8 serial maintenance
port connection exists on the faceplate. Do not connect two maintenance
terminals to both the faceplate and I/O panel serial maintenance port
connections at the same time.
Assembly description
The ITG-Pentium 24-port trunk card assembly consists of a two-slot
motherboard/daughterboard combination, as shown in Figure 9 "Mechanical
assembly" (page 51). A PCI interconnect board connects the motherboard
and the DSP daughterboard.
