Card Mismatch
Note Card mismatch is not reported when the front card is in standby. If the card becomes active and there is
a mismatch condition, the UXM-E will report a card mismatch.
The UXM-E uses a standard card mismatch notification for unsupported back cards.
If the front card was previously active, the UXM-E provides mismatch notification for supported back
cards featuring a different line type than the previously-installed back card, or if the back card has a
smaller number of the correct line types than what the UXM-E previously reported to switch software.
Attaching a back card with more ports of the correct line types does not trigger a card mismatch. If the
front card has not yet been activated, the UXM-E does not provide mismatch information for supported
back cards because a supported back card mismatch has not occurred.
For card mismatch examples, see Table 2-21.
Universal Voice Module
Table 2-22 shows the front and back cards supported by the universal voice module (UVM).
The universal voice module consists of a UVM front card and a universal voice interface (UVI) back
card with physical connectors for T1, E1, or Y1 lines. The module supports channelized T1, E1, or Y1
lines carrying voice, data, or voice+data traffic. For information on the connections supported by the
UVM, see Table 2-23.
UVM features include the following:
• Packet assembly and disassembly (PAD) for voice and data connections
• Software-configurable ports on the UVI back card
• A maximum of 32 channels per card
• Data connections at 64 kbps
• Super-rate data connections at nx56 or nx64 rates, where n ≤8
