Understanding configuration requirements
Understanding configuration requirements
You need the following information from your E1/PRI service provider:
• The telephone numbers assigned to your E1/PRI interface, channel-by-channel
• Nailed-up channels (also called private WAN), if any
• Unused channels, if any
• Switch type (or emulation)—DPNSS only
• Switch layers 2 and 3 configuration—Digital Access Signaling System (DASS) 2 and
DPNSS only (A/B end, X/Y end)
“Configuring the front-end E1
transceiver” on page 9-13
Set the front end type of the E1 transceiver to
Long-Haul or Short-Haul, depending on the
type of termination your line uses.

another. These are called add-on numbers.

“Configuring nailed channels” on
page 9-15
You must assign a nailed channel to a group
to make it available for use. The group
number can be referred to in a Connection or
Frame-Relay profile to specify a permanent
leased connection using that group of nailed
channels.

Chapter 19, “Configuring Call
Routing”
The TAOS unit uses call routing to determine
where to route incoming and outgoing calls.
The preferred way to set up call-routing is to
put all call routing information in one place: a
Call-Route profile.
If you do not use Call-Route profiles, specify
the physical address of a device to which
calls received on this channel are routed.
