Level 1 State Inquiry Test (#613)
This test is non-destructive.
This test determines the state of the transmission facility at the p hysical layer
(Level 1). This test is executed by the Packet Gateway circuit pac k for a port on a
command from the switch. The test p asses when the current status of the Data
Carrier Detect (DCD) and Clear To Send (CTS) If either of these leads are low, the
test fails.
If the port speed is ad ministered as a switched p ort then the CTS will always be
high but the DCD will be low on ly if there are transmission problems with the
FAIL The Packet Gateway circuit pack has detected a failure in the execution of the
test.
1. Verify that the Packet Gateway Local Loop-Around test (#610) passes.
Follow repair procedures for that test first if it fails.
2. Run test #611 for each external loopback position. If any test fails, then
take the action specified for that point:
a. Local Loopbac k (Loopback ‘‘B’’): Rep lace the external port c abling.
b. Digital Loopback (Loopback ‘‘C’’): Replace the data set.
c. Remote Loopback (Loop back ‘‘D’’): Investigate potential transmission
line problems. If necessary, escalate the problem to the party
responsible for maintaining the off-premise transmission network.
PASS Passing of this test for the following loopbacks indicates the integrity of the
following piece s of equipment:
1. Local Loopback (Loopb ack ‘‘B’’). Packet Gateway port hardware plus
cabling.
2.Digital Loopback (Loopback ‘‘C’’). Packet Gateway port hardware plus
cabling plus data set.
3. Remote Loopback (Loopback ‘‘D’’). Packet Gateway port hardware plus
cabling plus data set plus transmission line.
4. If all the above tests pass, place the port in-service (release port
UUCSSpp). Execute the status packet-gateway-port UUCSSpp
command and verify that the transmission-related error c ounters are not
increasing. Execute the ‘‘Link Status Test (#614)’’ via the test port
UUCSSpp command. Check out equipment at far-end if this test fails.
