Distributed Communications System
B Private Networking
In this case, the ETA Route Pattern routes undefined dialed strings. However, since
an ETA Node Number is not specified, non-call-related DCS messages are not routed.
CASE #3
• ETA Route Pattern — Not administered
• ETA Node Number — Administered
In this case, the ETA Node Number provides the route pattern. Non-call-related DCS
messages also can route since a node number is supplied.
CASE #4
• ETA Route Pattern — Administered
• ETA Node Number — Administered
In this case, the ETA Route Pattern routes undefined dialed strings while the ETA
Node Number routes DCS messages. Nodes themselves do not have to be
administered for ETA. ETA should not be used over tandem-tie trunks.
Interactions • Abbreviated Dialing
Abbreviated Dialing calls are routed via ETA.
• Attendant
Attendants calls are routed via ETA.
• Data-Call Setup
Analog and digital endpoints can access ETA. The digit string goes to the remote
switch like any other digit string is sent. The remote switch handles the data-call
setup from that point forward.
• Facility Restriction Levels
It is possible to restrict trunks that are being used in conjunction with ETA by
assigning FRLs.
• Last Number Dialed
If a number is routed via ETA to a remote switch and you want to reaccess that
number, then reaccess uses ETA.
• Modem Pooling
Modems in Modem Pools are treated like all other trunks.
• Remote Access
Remote-access trunks are able to access the ETA feature just as any other trunk or
station does.
