1014 NTCK16 Generic Central Office Trunkcards
Note: PPM is available on the NTCK16AX trunk card. It is not
supported on the NTCK16BX trunk card.
PPM allows the user of a telephone to keep an accurate record of Central
Office calls for billing or administration purposes.
Detection limits
Pulses detected by the NTCK16AX circuit card must be within the following
limits:
Frequency 11 880 to 12 120 Hz
Level 105 to 1100 mVrms
Note: The pack should not be used to
detect levels of 1100 mVrms or greater
a Tip and Ring, as this may result in
noise.
Pulse length Dependent on PPID – see LD 14
Busy tone detect
Busy tone is sent by the Central Office to indicate the release of an
established call.
Detection limits
The NTCK16AX and NTCK16BX generic Central Office trunk cards can
detect busy tone within the following limits:
Frequency 400 to 620 Hz
Level –30 to 0 dBm
Cadence See on page 803.
Loss switching
The Generic XFCOT is based on the XFCOTdesign, which is using a static
pad download algorithm by default for its loss plan.
The generic XFCOT has to be set explicitly to a Dynamic PadSwitching
mode to make it compliant with the standard North American Dynamic Pad
Switching mode.
Therefore the followingsteps must be followed when the Generic XFCOT
is installed:
1. Define Loss Switching mode. Respond to the prompts in LD 97 as
shown.
