Configuring T1 Cards

Overview of T1 configuration

Table 7-1. T1 line configuration tasks (continued)

Section	Description of task	Associated parameters
“Configuring nailed channels”	You must assign a nailed channel to a	Nailed-Group
on page 7-21	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.
“Configuring a back-to-back T1	For diagnostic purposes you might	Signaling-Mode set to Inband (the
connection” on page 7-21	sometimes want to configure a	default)
	back- to-back connectionT1 connection	Robbed-Bit-Mode set to
	between ports on two TAOS unit units.
		Wink-Start (the default)
		Clock-Source set to Eligible (the
		default)
“Specifying analog encoding for	Codecs connected to T1 use a different	Analog-Encoding
TAOS unit codecs” on page 7-22	encoding standard for digitized analog
	data than do codecs connected to E1.
	The default for T1 is U-Law, the default
	for E1 is A-Law.
“Configuring specialized	Typically, the D channel of a PRI line	Data-Sense
options” on page 7-22	uses normal data. However, for some	Idle-Mode
	connections, you might need to invert
	the data to avoid transmitting a pattern
	that the connection cannot handle
	Most installations use the default for the
	Idle-Mode setting, which determines
	what pattern the D channel looks for to
	specify the idle indicator.
Chapter 19, “Configuring Call	The TAOS unit uses call routing to	Default-Call-Type
Routing”	determine where to route incoming and	Call-by-Call-Service
	outgoing calls. The preferred way to set
		Shelf
	up call-routing is to put all call-routing
	information in one place: a Call-Route	Slot
	profile.
		Item
	If you do not use Call-Route profiles,
	specify the physical address of a device
	to which calls received on this channel
	are routed.
