Problems for network or remote users / 611 P0603534 02Modular ICS 6.1 Installer Guide Solution 1. Check the cross-connections for the E&M/DISA Trunk Cartridge. 2. If the E&M trunks are connected to another Norstar system, make sure that connections have been made as indicated in Installation on page 219. 3. Use the following table to check for correct voltage on the E&M/DISA leads: Voltages on E&M leads Dialed DISA number gets ringback instead of stuttered dial tone The remote caller has dialed a DISA number, but has instead reached a target line, or has been routed to the prime telephone for the auto-answer trunk. The Norstar system has mapped the incoming digits from a switch onto a target line, or has been unable to map the digits anywhere. Solution 1. Verify that the switch is sending the correct number of digits for the Received number length defined in your system. 2. Verify all the digit strings that the switch should be sending.

Make sure that the published telephone numbers for your network are correct. Dialed DISA number gets dial tone instead of stuttered dial tone Possible problem The remote caller has dialed a DISA number, but has reached the Norstar system instead. The Norstar system has mapped the incoming digits from a switch onto the Auto DN. Solution 1. Verify that the switch is sending the correct number of digits for the Received number length defined in your system. 2. Verify all the digit strings that the switch should be sending. 3. Check that you have defined the correct DISA DN for your system. 4. Make sure that the DISA DN and Auto DN are different enough to prevent misdialing. 5. Make sure that the published telephone numbers for your network are correct.
Problems for network or remote users / 613 P0603534 02Modular ICS 6.1 Installer Guide DISA user gets overflow tone when entering COS password Possible problem The remote caller may have entered an invalid password. Solution Check programming under COS passwords and verify that the caller has a valid password. Possible problem The remote caller may have entered an asterisk (*) as one of the six digits. Solution Instruct remote callers to enter their COS password correctly: enter six digits. Possible problem The remote caller may have entered a number sign (#) as one of the six digits. Solution Instruct remote callers to enter their COS password correctly: enter six digits. The number sign (#) may be entered after the sixth digit, but is not required.
614 / Problems for network or remote users Modular ICS 6.1 Installer GuideP0603534 02 Possible problem The remote caller may have waited more than 15 seconds between entering digits. Solution Instruct remote callers to enter their COS password correctly: enter six digits, and do not pause too long between digits. Possible problem The caller may be dialing from a rotary-dial telephone or from a push-button telephone that uses pulse signaling. Solution Inform remote callers that they must dial from a push-button telephone that uses DTMF tone signaling. Dialed feature code gets overflow tone Possible problem The remote caller does not have access to that feature. Solution 1. If the call came in on a trunk with DISA, check the Class of Service that is associated with the COS password of the remote caller. If it is too restrictive, modify the remote package assigned to the COS password, or assign another COS password that is more suitable. 2. If the call came in on a trunk without DISA, check the remote package that you assigned to the incoming trunk. Make sure that it gives the appropriate access to the remote caller.
Problems for network or remote users / 615 P0603534 02Modular ICS 6.1 Installer Guide Possible problem The feature code is not valid. Solution 1. Make sure that remote callers have a correct listing of the features that are programmed for remote access. 2. Ensure that remote callers are dialing the feature code correctly. Press • followed by the feature code to activate a remote feature. Possible problem The caller may be dialing on a rotary-dial telephone or on a push-button telephone that uses pulse signaling. Solution Inform remote callers that they must dial from a push-button telephone that uses DTMF tone signaling. Dialed feature code gets busy tone Possible problem A resource that the remote feature uses may currently be in use. For example, a remote caller trying to use the paging feature would get a busy tone if the auxiliary speaker were being used at the time. Solution If repeated attempts to use the remote feature get busy tone, there may be a malfunction in a resource that the feature uses. Check that the remote feature hardware is functioning normally.
616 / Problems for network or remote users Modular ICS 6.1 Installer GuideP0603534 02 Line pool access code gets overflow tone Possible problem If the published line pool access code is valid, the remote caller does not have access to that line pool. Solution If the incoming trunk answers with DISA, give the remote caller a COS password that permits access to that line pool. OR Change the remote package for the incoming trunk so that it permits access to that line pool. OR Give the remote caller a line pool access code that is permitted within the Class of Service on the incoming trunk. Possible problem If the published line pool access code is invalid, the system has attempted, without success, to match the invalid code to a Norstar target line internal number, and there is no prime telephone for the auto-answer trunk. Solution 1. Make sure that the published line pool access codes are correct.
Problems for network or remote users / 617 P0603534 02Modular ICS 6.1 Installer Guide 2. Check that the line pool access codes have been entered correctly under Access codes in System prgming. Possible problem The caller may be dialing from the network on a rotary-dial telephone or on a push-button telephone that uses pulse signaling. Solution Inform remote callers that they must dial from a push-button telephone that uses DTMF tone signaling. Line pool access code gets ringback Possible problem The published line pool access code is invalid, and the system has routed the call to the prime telephone for the incoming trunk. Solution 1. Make sure that the published line pool access codes are correct. 2. Check that the line pool codes have been entered correctly under Access codes in System prgming.
618 / Problems for network or remote users Modular ICS 6.1 Installer GuideP0603534 02 Line pool access code gets busy tone Possible problem There are not enough lines in the line pool to serve the number of users. Solution If the line pool contains loop start trunks, enter programming and move under-used loop start trunks from other line pools into the deficient line pool. OR If the line pool contains E&M trunks, order more trunks from the telephone company or private network vendor. Install additional E&M Trunk Cartridges. In programming, add the new trunks to the deficient line pool. OR Create a separate line pool for remote users only. Possible problem There are DID lines in the line pool. Solution In programming, make sure that there are no DID lines in any of the line pools.
Problems for network or remote users / 619 P0603534 02Modular ICS 6.1 Installer Guide Dialed number gets no response Possible problem The remote caller, after accessing a line in a line pool, may have started dialing before the far end was ready to receive. Solution Instruct remote callers to wait until they hear feedback before entering any digits. Possible problem There may be a malfunction in the line that the remote caller accessed. Solution If the problem is persistent, check that all lines in the affected line pool are functioning normally. Possible problem There may be a malfunction in the system that the caller is trying to reach. Solution Inform the operators of the system at the far end that the dialed number is not getting through.
