List of terms

exterior reachable address

An address that a node can reach through a PNNI routing domain but that is not located in that PNNI routing domain.

external address plan (EAP)

An address plan that is not the Nortel Multiservice Switch internal address plan. Examples of EAPs are a DPN internal address plan and an IP address plan.

external border gateway protocol (EBGP)

BGP configuration in which sessions are established between routers in different autonomous systems (ASs). See also border gateway protocol (BGP) (page 20) and multi-hop BGP (page 83).

external gateway (EG)

Aconnection to a non-Nortel Multiservice Switch external module (for example, a connection to a DPN-100 module).

exterior gateway protocol (EGP)

An IP routing protocol that operates between autonomous systems on the Internet. BGP-4 is replacing EGP.

external routing protocol

A routing protocol from another network. Routing of external protocols is done either natively or using encapsulation. External protocols are routed natively when the packet is routed directly according to the address contained in its header. Encapsulation is used to completely envelop the external protocol within a Nortel Multiservice Switch packet, using it for making routing decisions.

fabric card

The circuit pack that performs the cell-switching activities between the processor cards of a Nortel Multiservice Switch 15000, or Multiservice Switch 20000 node.

fabric port

An interface to the fabrics of a Nortel Multiservice Switch 15000, or

Multiservice Switch 20000 node.

facsimile handling

The handling of in-band facsimile or modem data dynamically. On detection of a facsimile or data call, echo cancellation is disabled and the voice compression rate is adjusted to allow the facsimile or data information to be transported to its destination.
