CONVENTIONAL CHANNEL MODULE (CCM)
9-10
9.2.4 CCM BACKPLANE EXTERNAL
CONTACTS
See Backplane Section 23 for pinouts on the shelf
backplane and wire harness pinouts.
9.3 CCM ALIGNMENT SPECIFICATIONS
9.3.1 PRE-ALIGNMENT
The CCM is pre-aligned with the Basic Board
Module alignment procedures, Refer to Section 7.3.
9.3.2 CCM ALIGNMENT PROCEDURE
Connections to the CCM may take several forms:
1. Direct Connection
2. Leased Lines
3. Microwave Link
4. T1 Channel Bank Interfaces
This ancillary equipment requires certain input
and output levels for proper operation. The module
should be adjusted accordingly.
Main Transmit
1. Determine the maximum level to be received by the
ancillary equipment to be transmitted.
2. Select Test 1 (S5, open section 1, close sections 2, 3
and 4).
3. Reset the module, Press S2 and release.
4. Adjust R44 for -12 dB from the maximum level in
Step 1 at J12.
5. Select for normal operation (S5 all sections closed).
6. Reset the module, Press S2 and release.
Example: Microwave has -16 dBm max input, Set
J12 for -28 dBm.
Main Receive
1. Determine the maximum transmit level that is sent
by the ancillary equipment to the interface module.
2. Select Test 1 (S5, open section 1, close sections 2, 3
and 4).
3. Reset the module, Press S2 and release.
4. Insert the maximum level determined in Step 1
using a 600 ohm audio oscillator into EQU port of
J1. Otherwise, set the ancillary equipment to send
the maximum level alignment tone to the interface
module.
5. Adjust R41 to be -6 dBm at J11.
6. Adjust R102 to be 0 dBm at TP8.
7. Select for normal operation (S5 all sections closed).
8. Reset the module, Press S2 and release.
Example: Microwave has +7 dBm maximum
output, set J11 for -5 dBm.
