Identifying the AXSM Models

The model number of an AXSM identifies the line speed, line count, and number of bays (see

Note that the number of lines applies to an individual back card, so the total number of lines supported

by the front card equals the highest line number times the number of bays. The OC-48 card

AXSM-1-2488 has the lowest number of lines—one. The highest number of lines exist on the

AXSM-16-155 and AXSM-16-T3E3—16, as the name indicates.

The MGX 8850 node use the concept of a bay. The bay refers to the upper or lower location of a

single-height card. (The switch has a double-height card cage, so a single-height back card necessarily

occupies either an upper or lower position.)

The T3/E3, OC-3, and OC-12 versions of the AXSM can have two back cards, one in bay 1 (upper

location of the back slot) and the second in bay 2 (lower slot). The MGX-AXSM-1-2488 (OC-48 AXSM)

can have a back card in bay 1 only. For further descriptions and illustrations of the card sets, refer to

Cisco MGX 8850 Hardware Installation, Rel 2.0.

The SVC and SPVC connection capacities for the front card, back card, and physical lines appear in

Nevertheless, the tables provide these maximums when you plan the use of commands such as

addrscprtn, addcon, and any other command where you may want to know the capacity of the

configured item to support connections.
