7. Program the cards as described in “Configuring the Meridian 1 for the
Meridian Companion system” on page 103.
Optimizing Card Slot Usage
You can optimize the card configuration by enabling the double density
feature (32 WTN) and replacing CMRC or CMLC cards with CMBC cards.
Users registered on the CMRC/CMLC cards being removed must be
MANUALLY reregistered onto new WTN positions created on each of the
remaining CMCC/CMRC cards. Automatic relocation of registration data is
NOT provided. These relocated users must also be moved to the
corresponding TN positions on the Meridian 1.
If a CMBC card is to be added to the card configuration, additional radio
credits may be required.
Replace CMRCs or CMLCs at the right hand end of the system with CMBC
cards to expand a system. Whereas normally this type of card configuration
change would cause an exception condition (see “Config failure:
Nonrecoverable inconsistency” on page 161), the change can be accomplished
using the following procedure.
The following procedure outlines the process for replacing CMRC or CMLC
cards with CMBC cards
1. Perform the system upgrade from DRx to DR4, but DO NOT
EXECUTE RE-EVAL.
2. Clear all programmed portable data from the CMRC/CMLC cards to be
removed.
a. De-register portables from the WTNs.
b. Remove any radio loss handling data for these WTNs (see
“Programming Call Transfer on Radio Loss” on page 115).
c. Retain wireless TN datafill until step 8.
3. Disconnect the appropriate faceplate cables and remove the
CMRC/CMLC cards to be replaced.
4. After the "Failed" alarms appear for the disconnected cards (i.e. Alarms
51/52 as appropriate), DISABLE then RE-ENABLE each of the
