I am presently in the process of intregrating a few exchanges for a public limited company, and in the process, I need to connect a CORAL III exchange (through 30TM cards) to PCM MUX via E1 links.
Can anybody tell me about the exchange configuration needed for the same? Does E1 connection allowes 30 simultaneous bi-directional voice channels, or do I need to split the 30 channels in inwards/outwards directions?
