C.2.3 Setting Up Transceivers
Configure the modems first for EDMAC operation, setting up the Remote Control
Address (RCA) for local units, and ESA (EDMAC addresses) for EDMAC modems. A
transceiver's address will be set automatically by its controlling modem if connected
via the FSK link when the ODU enable is configured.
•
Local Transceiver 1
(linked to Modem m on the Switch):
o
First, set up the modem RCA, as described in Section C.2.2.
o
On the modem, key to Enable ODU.
The modem automatically sets the transceiver address:
Transceiver MCA = (Modem RCA) + 1.
•
Local Transceivers 1 & 2
(1:1 configuration, attached to Modem m on the Switch):
o
First, set up the modem RCA, as described in Section C.2.2.
o
On the online modem, key to Enable ODU.
The modem automatically sets the transceiver addresses:
MCA of Transceiver #1=(Modem RCA)+1
MCA of Transceiver #2=(Modem RCA)+2
•
Distant Transceiver 1
(stand-alone):
o
First, set up the modems, first, as described earlier in this section. .
o
On the modem, key to Enable ODU.
The modem automatically sets the transceiver address:
Transceiver MCA=(Master ESA)+4=(Slave ESA)+3
•
Distant Transceivers 1 & 2
(1:1 configuration):
o
First, set up the modem, as described earlier in this section.
o
On the modem, key to Enable ODU.
The modem automatically sets the transceiver addresses:
MCA of Transceiver #1 = (Master ESA) + 4
MCA of Transceiver #2 = (Master ESA) + 5
