Interconnect Extension Circuits (IECs) provides you with the ability to extend the reach of your network, by providing a 2Mbit/s circuit from an In-Span Interconnect (ISI) Point of Connection (PoC), to a remote BT switch location via BTs network.
You would usually interconnect with BT at the most cost effective and convenient point that your network allows (outside a BT exchange). Where it is impractical for you to develop your physical network to a remote BT switch, an IEC via the existing PoC will enable connectivity.
IECs are only available in conjunction with In-Span Interconnect (ISI) circuits.
