	following components are connected: port, tone-clock, maintenance,
	service, and (optionally) expansion interface circuit packs. Every port
	network in a PBX is controlled by the PBX processing element in the
	processor port network (PPN).
pooled	Shared “conversion resources” (modems and data modules) that provide
modems	cost-effective access to analog facilities by data terminals. When
	necessary, modem pooling inserts a conversion resource into the path of
	a data call. Modem pooling serves both outgoing and incoming calls.
port	A data- or voice-transmission access point on a device that is used for
	communicating with other devices.
port network	See PN.
private	See PBX.
branch
exchange
private	A network used exclusively for the telecommunications needs of a
network	particular customer.
processor	See PDM.
data module
proxy	The mechanism in which one system emulates another system in
	responding to protocol requests. Proxy systems are used in network
	management to avoid having to implement full protocol stacks in devices
	like modems.
Proxy Agent	Software that converts management information from a DEFINITY G3 PBX
	into a format that your network management system can understand.
proxy string	The second element of the community name. For the Proxy Agent, this
	string is always “g3mgt.”
public	The network that can be openly accessed by all customers for local or
network	long-distance calling.
