“Configuring nailed channels” on	You must assign a nailed channel to a group	Nailed-Group

	number can be referred to in a Connection or
	Frame-Relay profile to specify a permanent

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)
