expansion archangel (EAA)
A network-control microprocessor located on an expansion interface (EI) port circuit pack in an expansion
port network. The EA provides an interface between the EPN and its controlling switch-processing element.

expansion-archangel link (EAL)
A link-access function on the D-channel (LAPD) logical link that exists between a switch-processing element
and an expansion archangel (EA). The EAL carries control messages from the SPE to the EA and to port cir-
cuit packs in an expansion port network.

expansion control carrier
A carrier in a multicarrier cabinet that contains extra port circuit packs and a maintenance interface. Also
called expansion control cabinet in a single-carrier cabinet.
called expansion control cabinet in a single-carrier cabinet.
expansion interface (EI)
A port circuit pack in a port network that provides the interface between a PN’s TDM bus/ packet bus and a
fiber-optic link. The EI carries circuit-switched data, packet-switched data, network control, timing control,
and DS1 control. In addition, an EI in an expansion port network communicates with the master maintenance
circuit pack to provide the EPN’s environmental and alarm status to the switch-processing element.

expansion port network (EPN)
A port network (PN) that is connected to the TDM bus and packet bus of a processor port network (PPN).
Control is achieved by indirect connection of the EPN to the PPN via a port-network link (PNL). See also

Expert Agent Selection
A feature allowing incoming calls to be routed to specialized groups of agents within a larger pool of agents.
extension-in
Extension-In (ExtIn) is the work state agents go into when they answer (receive) a non-ACD call. If the agent
is in Manual-In or Auto-In and receives an extension-in call, it is recorded by CMS as an AUX-In call.

extension-out
The work state that agents go into when they place (originate) a non-ACD call.
external measurements
Those ACD measurements that are made by the External CMS adjunct.
extension
A 1- to 5-digit number by which calls are routed through a communications system or, with a Uniform Dial
Plan (UDP) or main-satellite dialing plan, through a private network.
