The DS3XM-6 card works in conjunction with the XCVT card. A single DS3XM-6 can demultiplex six
DS-3 signals into 168 VT1.5s that the XCVT card then manages and cross connects. XCVT cards host
a maximum of 336 bidirectional VT1.5s on two DS3XM-6 cards. In most network configurations, two
DS3XM-6 cards are paired together as working and protect cards.
