Figure 9-77. Packet Gateway Port Remote Loop-Around Test
Manual activation of the loopback is required for this test. If available, the Local
Loopback (B in the above figure), Digital Loopback (C), and Remote Loopback
(D) capabilities of external data sets may be used in conjunction with this test for
fault isolation. Execution of this test with the data set in the Local Loopback mode
verifies the integrity of the external port cabling. Execution of this test with the
data set in the Digital Loopback mode verifies the integrity of the data set.
Execution of this test with the far-end data set in the Remote Loopback mode
verifies the integrity of the transmission facility.
For this test to run, the port or link must be busied out and the ‘‘Remote
Loopback’’ field on the data-module form must be set to ‘‘y.’’ This field should
only be set to ‘‘y’’ when the external loopback switch has been activated for the
test, and should be changed back to ‘‘n’’ when testing is completed and the
external loopback has been deactivated.
To test to an MPDM attached to a Packet Gateway port:
1. Enter
busyout data-module
extension or
busyout port UUCSSpp
or
busyout link
link#.
2. Set the switch on the MPDM to local loopback.
3. Enter
change data-module
extension and set the ‘‘Remote Loop-Around
Test’’ field to ‘‘y.’’
4. Enter test data-module extension long or test port UUCSSpp long or
test link link# long.
5. When finished testing, enter change data-module extension and set the
‘‘Remote Loop-Around Test’’ field to ‘‘n.’’
6. Enter release data-module extension or release port UUCSSpp or
release link link#.
To test through an administered connection to an MPDM attached to an adjunct
(see ‘‘Packet Gateway Configurations’’ at the beginning of the PGATE-PT
section):
