| No Dial Tone Is this your only analog line card in the system? If it is, and you set the CLS on the 500 ports to DTN, do you have any DTR's defined in the system? If there are no DTR's available, you will not get dial tone if the stations are DTN. The DTR's are part of the core card and should be programed as TN's 0-0 through 0-7. |
