The remainder of this chapter describes each option within the Diagnostic Menu screen.
Use Set Up Path to create a voice path between two ports (referred to as A and B). A voice path is a physical, system-switched connection that allows the transfer of in-band signaling and/or voice energy. In-band signaling can consist of MF or DTMF digits, tones, or voice prompts. Ports can be specified by hardware or software address. Port A and Port B do not have to be linked into the same resource chain in order to create a voice path.
System resources are divided into two categories:
When you create a voice path, you must designate one port as the sender and one port as the receiver. Table 6-1 lists the valid system senders and receivers.
| Senders | Receivers | Senders and/or Receivers |
|---|---|---|
Tone channels | DRC ports | SLIC ports |
DVC ports | MRC ports | DID ports |
IPRC ports | CPA ports | UTC ports |
— | MFCR2 ports | Single span T1 channels |
— | — | Single span E1 channels |
— | — | PRI B-channels |
— | — | E+M ports |
— | — | DCC ports |
— | — | Four span T1 channels |
— | — | Four span E1 channels |
— | — | MVDC T1 channels |
If both ports specified can send and receive, a two-way voice path is created. Otherwise, the voice path is one way. Up to eight voice paths can exist simultaneously.
When you create a voice path from the Set Up Path function, the system first checks to see if both ports are removed from service. Refer to the "Changing the Status of a Port" section for more information on changing the status of a port.
You can also create paths using the Voice Path Control ($66) command. Refer to the Cisco VCO/4K Standard Programming Reference and the Cisco VCO/4K Extended Programming Reference for more information.

Use Test Service Circuits to test individual circuits on DTMF Receiver Cards (DRCs), MF Receiver Cards (MRCs) and Call Progress Analyzer cards (CPAs). You can test any or all receiver ports on the same card with a single command. Ports are tested in sequential order from the start port you specify to the end port you specify. You can also set this test to loop continuously so that each port is tested in sequence. The cycle is repeated until you terminate it.
When testing a DRC or MRC, a path is set between the selected circuit(s) and an outpulse channel; digits are then sent to that receiver. The system compares the digits sent with the digits received. If any discrepancies are detected, an error message and the two digit strings are sent to the error log and the system printer.
When testing a CPA card, dial tone, ringback, ringback cessation, busy, and reorder tone events are presented by the Digital Tone Generator (DTG) card to the CPA port(s) for detection. Any discrepancy between the presented tone and the reported detection is pegged as a test failure for the CPA port(s). Logfile and system printer error messages specify the port's address and the type of tone it failed to detect.
A port on a line/trunk or receiver port can be used to monitor the test. This port listens to the voice path between the service circuit being tested and the resource providing test digits or tones. By monitoring the digits and tones being passed, you can determine the exact point of test failure.
From the Card Maintenance screen, place the card on which the receiver ports reside in Diagnostic mode before you test it. If the card is not in Diagnostic mode, an error message appears and the test command is aborted. Take the port out of service from the Card Maintenance screen or a Change Port Status ($90) host command (refer to the Cisco VCO/4K Standard Programming Reference and the Cisco VCO/4K Extended Programming Reference).
If any ports are active when the card is placed in Diagnostic mode, the card automatically goes into Camped On mode. The Service Circuit Test function can be run on a card in Camped On mode; the test skips any nonidle ports on the card.

Monitor R,L,S,P—Data entry via main keypad. Four fields that specify the physical location (R,L,S,P port address) of a port on a line/trunk card or receiver card used to monitor the test. This port monitors the reception of test digits, spoken digits, and call progress tones. Possible port types include:
Start Test at Port—Data entry via main keypad. Specifies the port with which to begin the test. If you do not specify a Start Test at Port value, the test is not performed. Valid values are determined by the number of ports supported by the card type:
End Test at Port—Data entry via main keypad. Specifies the port with which to end the test. If you do not specify a value, or the value is less than or equal to the start port value, only the port contained in the Start Test at Port field is tested. Valid values are determined by the number of ports supported by the card type:
Print Error Messages Only (Y/N)—Data entry via main keypad. Specifies whether to display and print test results as the test is being conducted or only if an error occurs.
