Thankyou for this, but this is the procedure i have been using without success. i tried it again now with the same (lack of) result. What is interesting is that the messages do not appear at the central office, but if CM08>800 is then changed to 0, the messages will then magically be received...

i am attempting to use an AP00B in a NEAX2000IPS that is local office in a network with Centralized Billing. According to the book it should be possible and work uisng the AP00B to buffer billing records, but i find that with the AP00B installed that billing messages are not sent to the central...

1. Framing and timing errors are indicative of a synchronizing problem between the two PABX. Do you have SCEXI set at the appropriate PABX for receiving the Frame synch? This should only be set at one end of the link, the other end being the Clocking Master. Are both PABX using CRC-4...

Can you supply the MFC signal defnitions used in Cambodia?

Yes it is possible to provide a basic QSIG link on MD110 from BC6.0 onwards but it will only provide for simple call handling with number presentation/restriction facilities. There is no enhanced networking available. Note also that the QSIG is ISO QSIG (Codeset 4), not ETSI QSIG. i used the...

i assume you are using a Nokia Fixed Wireless Terminal connected to a trunk (Ring/Loop, TL11 or similar) on the MD110. If this is so, then you should check the following: 1. Is the trunk looking for an Answer signal (polarity reversal) when the cellular call is connected - check in Route...

You may like to explore any of the following: - SHDSL modems in 2-wire or 4-wire mode with one or more SHDSL repeaters (Lucent Cellpipe, Verilink Wansuite, RAD LA-110, etc); - HDSL modems in 2-wire or 4-wire mode (Nokia, Pair Gain systems, etc); - Use recovered PCM Digital Line Terminals as...

Fouesnant In response to your question about the purpose of CRC4, the following may assist. With the introduction of ISDN it is possible for users to transmit data over a 64 kbit/s clear channel. The problem with this is that it is possible for user equipment to transmit the bit pattern...

Note that the distance is realted to conductor gauge, the lighter the gauge the shorter the distance. It is more properly expressed as the length that gives a 6 dB loss at 1024 kHz.

Reliability and failure are statistical. These are normally expressed in mean time between failure as being so many hours, months or years. This means that the more of an item in service in the world, then the more the total number of failures that can be expected, and will actually occur...

The following test instruments can be used for CAS 2,048 Mbit/s monitoring: Ameritec AM-8e Elmi EPR-31 Elmi EPC-91 STR PCMX-30

i would check the setting of the SIG parameter in the route category.

Suggest you check the following: 1. Are you sending sufficient digits to the Nortel PABX? 2. Is the Nortel set up for Decadic or DTMF digit reception? 3. Is the MD110 looking for Dial Tone before sending digits to the MD110?

i currently have a network with BC.7.2.1 using TLU76/1 with QSIG to a BP250 R12. Basic call setup operates satisfactorily but there is little functionality apart from this. In this network the MD110 is acting as the ISDN Master on the link to the BP250. The MD110 is also the clock source for...

Singhbrindisi: Can you still dial in Decadic Pulses to set up calls when you encounter the dialling failure?
