Support of AT&T’s
4ESS Switch Protocol
You can select AT&T’s 4ESS switch protocol when you configure a T1
Digital Line Card for PRI (Primary Rate Interface) operation. If you select
the 4ESS protocol, you can optionally use Call By Call Service
Configuration which enables you to select one of three access services:
■
Long Distance — The default service if the customer selects the 4ESS
protocol, but purchases no other services. Long Distance can be used
with SDN but not with MEGACOM.
■
MEGACOM — A high-volume outward calling service. MEGACOM
can be the default setting.
■
SDN (Software Defined Network) — A premises-to-premises service
with voice and voice-grade data transport, plus a number of
customer-controllable call management and call monitoring features
(for example, Virtual Private Networking). You cannot configure SDN
as the default setting but you can configure the NBX system dial plan
to use SDN.
