(1) Line Loopback
The line interface part of MG-PRI/PRA sends back all the channels from ISDN network. Normally,
this loopback will work with the timing of ISDN.
(2) Payload Loopback
The speech control part of MG-PRI/PRA sends back all the channels from ISDN network. Differing
from Line Loopback, a part of Payload Loopback will work with the timing of ISDN; an error will oc-
cur unless MG-PRI/PRA and ISDN are synchronized.
