Service Diagnostics allow the user to detect PL1877A hardware problems. The PL1877A cannot remain
in communication with the IAPS while performing the remote diagnostics. Therefore, results of the
remote diagnostic session must be read at least 15 seconds later. The following information is reported:
• Default parameters have been reloaded since remote diagnostics were last performed.
• Autodial memory has been modified by a mobile user since the remote diagnostic was last
performed.
• For Telephone Line 1 and 2 PL1877A is currently disconnected from the phone line.
• An attendant phone on the phone line is off-hook, or the PL1877A is disconnected from the phone
line.
• PL1877A is programmed for the wrong talk battery voltage on the phone line or the PL1877A access
control circuitry is damaged.
• Audio path between the DSP processor and the phone line is damaged.
• DSP-HCII Error #l
• DSP-HCII Error #2
• DSP-HCII Error#3
