  • Page 16: Signalling Specification

    If a wake up signal, e.g. a polarity reversal, is sent out to initiate CLIP, the terminal will draw a short current pulse which can be interpreted by the SUPM1 as an off-hook event. So the detection time for off-hook has to be increased to prevent this false off-hook detection to ≥...
  • Page 17 In the MCAS mode of operation, the flash detection times are defined by the CAS. Note: If SUPM1 is in thermal overheat state 1 and a flash impulse is > 200 ms, then this flash impulse will interrupt the call since it is detected as a short but valid on-hook state.

  • Page 45: Pstn Maintenance

    PSTN Maintenance If for maintenance purposes a subscriber has to be removed from the MDF (main distribution frame) or a SUPM1 unit has to be removed from the XMC20 subrack, this should be done without interrupting ongoing calls. This is accomplished, under the control of the signalling (H.248/MEGACO, SIP or V5), by blocking a user port as soon as an ongoing call is terminated.

    Note that the theoretical load capacity of a PCM A-law coded signal is +3.14 dBm0. With a relative level of 0 dBr, the maximum absolute level is therefore 0 dBr + 3.14 dBm0 = 3.14 dBm. © KEYMILE December 2015 page 48 of 94 EN/LZTBU 372 129/1 RC...

  • Page 49: Line Feeding

    User Manual SUPM1 Line Feeding The analogue a/b-wires of SUPM1 are fed with a line feed current, the loop current. This is the current a subscriber will draw from the interface during off-hook. Since the interface behaves as a constant current source it is possible to define the value of this constant current (= maximum loop current) in the range from 15.0 mA up to 45 mA.

  • Page 50: Signalling

    On unit level, advanced board parameters, the “Metering Pulse after On Hook” can be configured. This timer defines the time a SUPM1 user port may send out any metering pulses after the subscriber went on-hook. Also the voice path remains transparent during this time.
  • Page 51 An initial ring or a polarity reversal signal is used as an indica- tion that CLIP will follow as in-band tones. In support of CLIP, the SUPM1 unit opens the voice path to the line upon reception of any PSTN CAS signal in the on-hook state.

  • Page 52: Line Test

    A line-test is started either manually (on demand line-test) or automatically in a user-defined interval (cyclic line-test). The SUPM1 checks for each subscriber whether he is busy or idle. If a sub- scriber is busy (off-hook or ringing) the line-test for this particular subscriber is postponed.
  • Page 53 A reasonable time to start the test is between 2am and 4am since then the traffic is low. Please keep in mind that a line-test for an entire SUPM1 will typically take about 3 minutes and up to 8 minutes in the worst case.

  • Page 55 The resulting line-test status is displayed as follows: • Requested In this phase the SUPM1 checks the subscriber line for its state (on-hook / off-hook). If a subscriber is on-hook the user port is set to the locked state (V5CAS mode of operation only).
