Chapter 4 Card Reference
XC10G Cross-Connect Card
4.9.2 XC10G Hosting DS3XM-6
The XC10G card works with the DS3XM-6 (transmux) card. A single DS3XM-6 can demultiplex (map
down to a lower rate) six DS-3 signals into 168 VT1.5s that the XC10G card manages and cross
connects. XC10G cards host a maximum of 336 bidirectional VT1.5 ports. In most network
configurations, two DS3XM-6 cards are paired as working and protect cards.
4.9.3 XC10G Card-Level Indicators
The XC10G faceplate has two card-level LEDs.
4.9.4 XC/XCVT/XC10G Compatibility
The XC10G supports the same features as the XC and XCVT cross-connects. The XC10G card is
required for OC-192 and OC-48 any-slot operation. Do not use the XCVT or XC cards if you are using
the OC-192 card, or if you placed one of the OC-48 any slot cards in a multispeed slot.
