Decreasing channel numbering sequence
Table 43 "Channel numbering error – decreasing channel number sequence"
(page 190)
shows an example of a decreasing ISL channel numbering plan.
Using decreasing ISL channel identifiers causes the IP trunk card to be
unable to associate the ISL channel number with the B channel number. In
this example, only unit 0 (loop shelf card 0) can be used.
Table 43
Channel numbering error, decreasing channel number sequence
Unit number (from TN) ISL Channel number
0 24
1 23

3 21

6 18
7 17
Overlapping channel numbers
Do not provision the ISL channel numbers on both cards with the same
channel numbers. For example, do not configure Channel 10 on both
cards. The Meridian 1/CS 1000M rejects this numbering plan but the IP
trunk card does not. Therefore, it is possible to implement the incorrect
card numbering, making all channels above the first overlapping number
unusable.

Card installation procedure
CAUTION
CAUTION WITH ESDS DEVICES
Use ESD precautions when unpacking the hardware and
unpacking the cards.
Place each IP trunk card in the Meridian 1 or CS 1000 system and record
the TN, ELAN MAC address, and card density on the IP Trunk 3.01 (and
later) Installation Summary Sheet. The ELAN MAC address is labeled on
the IP trunk card faceplate as the motherboard Ethernet address.
