HYB-LINE (Hybrid Line)
Issue 1 June 2005 1331
Notes:
a. Error Type 1: The data link between the port and the terminal is not operational. (An
off-board problem was detected by port circuit). Verify that the Hybrid set is connected and
that the Electronic Power Feed (EPF) test passes. If data transmission problems are
experienced, check for defective wiring or a defective voice terminal, or move terminal
closer to the switch (reduce the length of the wiring between the terminal and the switch). If
the problem persists, replace the circuit pack. Once the problem has been resolved, the
alarm will be retired after a predetermined delay.
b. Error Type 18: the port is busied out. The port is released with release port
location.
c. Error Type 130: the circuit pack has been removed or has been insane for more than
11 minutes. To clear the error, reinsert or replace the circuit pack.
d. Error Type 257: the EPF has been turned off due to an overcurrent condition at the voice
terminal. Check for defective wiring or a damaged jack, and make sure the voice terminal is
a Hybrid set. Once the problem has been resolved, the alarm will be retired after a
predetermined delay.
e. Error Type 513: the voice terminal has been disconnected or there is a problem in the
wiring to the terminal. Make sure that the voice terminal is connected or check for defective
wiring to the voice terminal.
f. Error Type 769 and Error Type 1281: by themselves create Warning alarms. If both are
present, a Minor alarm is logged.
g. Error Type 1281 or 1537: the port has reported a problem with the data link to the voice
terminal. Ignore this error if there are no complaints about the voice terminal. Otherwise,
make sure the voice terminal is connected, check for defective wiring, check for a defective
voice terminal, and decrease the length of the wiring between the voice terminal and the
switch. If the problem persists, replace the circuit pack.
h. The voice terminal went off-hook while in the disconnect state. Use status station to
determine the state of the terminal. The off-hook should have moved the terminal to in
service. No repair action is necessary.
i. Error Type 2049: the link between the circuit pack and the voice terminal has been
successfully reset. No repair action is necessary.
j. Error Type 15: a software audit error that does not indicate any hardware malfunction. Run
the short test sequence and investigate any errors.
