4. EPF, M, and E Lead Test ABORTS on trunk ports administered as access
endpoints. This test consists of two parts:
■
E lead test—Checks for the proper activation and deactivation of the
port’s E lead.
■
M lead test—Checks the M lead EPF current flow. The results of this
test allow for distinguishing between circuit pack and external facility
failures.
5. Port Audit Update Test (Audit & Update Test for the TN497 circuit pack)—
Sends non-disruptive administrative updates to the circuit pack with no
expected response. The test updates the translation information on
individual ports of the Tie Trunk. Except for the TN497 circuit pack, these
updates include:
■
Immediate, automatic, wink start, or delay dial; for the TN2140B,
continuous-seize-ack
■
For the TN2140B, continuous or discontinuous.
■
Rotary or DTMF senderization in or out
■
Disconnect timing
■
DMTF time slot
Additional in-line testing is performed while a call is in progress. Thus, many
in-line errors may occur during operation. See the Error Log table for a description
of these errors. These errors may be reproduced by using the trunk (making a
call), and checking their occurrence in the Hardware Error Log.
Before a maintenance test can be run on a port, the port is required to be idle.
Except for a TN497 circuit pack, if an incoming call seizes the port which is being
tested by maintenance, the test is aborted, and the incoming call proceeds.
Non-TN497 circuit packs can be configured for back-to-back testing (also known
as connectivity testing) by making translation and cross-connect changes. This
testing configuration allows for the connection of Tie Trunks back-to-back in the
same switch to verify the operation of Tie Trunk ports. The tests can be performed
in either the E&M or simplex modes.
