Q: Does the MH360 support signalling system 7 (SS-7) on all 32 channels?
A: No. The MH360 does not support SS-7. Run the SS-7 microcode on a normal
Q: Is any extra support logic required to attach an MH360 to an ISDN primary rate line?
A: Yes, a T1 transceiver and framer unit will be needed. Manufacturers include Dallas
Q: Can the MH360 be used as an ISDN basic rate terminator?
A: Yes, send multiple Motorola U Interface outputs into a single SCC using the QMC
Q: 360 documentation says that the time slot assigner can be used with all of the SCCs
A: Yes.
Q: What is the maximum bus latency at 25 MHz when using 32 64-Kbps channels?
Q: Can TDM
A: Yes.
Q: Can the transparent channels of the MH360 (QMC mode) synchronize on an inline
A: No.
• For loopback on an individual time slot, set bit 15 of the corresponding entry in
For the last two methods, use a common transmit/receive clock and transmit/receive
sync pulses. Also in these last two methods, if the loopbacked data is to be received
on the same virtual channel, make sure the transmit and receive portions of your SI
RAM entries match.

and the SMCs. However, the MH360 reference manual states that the time slot
assigner works with the SCCs. Can the time slot assigner work with the SMCs?
A: Nine clocks. It is very important. At 25 MHz, the CPM is just able to empty the
FIFO quickly enough to prevent underrun. If the part is run at 33 MHz or if only 24
channels are needed, the margin increases allowing for a better worst case.

transmit time slot 1, but virtual channel 5 could be assigned to receive time slot
1. Therefore, global loopback would cause the data transmitted on channel 1 to
be received on channel 5.
