It also connects to the external E1 connections. This allows to +adapt the BTS to specific E1 networking requirements that may differ from the +usual timeslot configuration. + +The internals of an Ericsson RBS are quite complex. In the following we will +only explain how to connect transceiver units (TRU) to an E1 interface pointing +to the outside world. + +==== Understanding the is-connection-list VTY option + +The IS operates on 16kbps subslots (ICPs), which means that there are no fixed +borders between E1 timeslots. Any number of consecutive subslots may be +connected through. However, depending on the components that are connected it +may still be a requirement to align on E1 timeslot borders. + +The configuration of the IS is done using the is-connection-list command. The +first two numbers are the ICP numbers that specify the first subslot on both +sides that shall be interconnected. The third number (contiguity index) specifies +how many of the following subslots shall be connected. + +In the following example we connect 4 blocks with 12 subslot each. The numbers +on the left are the ICP numbers of the E1 connection pointing to the outside. +The numbers in the middle are the ICP numbers of the subslots occupied by the +transceivers (one TRX per block).

The solution to this was to add an entirely new set of IS +ICPs where full 64kbps E1 timeslots instead of 16kbps subslots could be +used to serve a single air interface timeslot.
