3Com 11.3 manual Decimal. The Dlci identifies a virtual circuit on the Frame, @22, Number, 107.44

		Learning About the User Interfaces 31
Frame Relay	Requires an address called a Data Link Connection Identifier (DLCI).
	DLCIs are assigned by the appropriate authority at subscription
	time. A DLCI follows an at sign (@) and can range from 1 through
	1022 decimal. The DLCI identifies a virtual circuit on the Frame
	Relay network, and is used by the local bridge/router to send a
	packet to a router on the other end of the circuit. The following is
	an example of a Frame Relay address:
	@22
	In the standard (local) addressing convention, the DLCI number has
	only local significance; a duplicate number can be used by other
	bridge/router or tunnel switches. In the global addressing
	convention, identifiers used throughout the Frame Relay network
	are unique, and all traffic to a node has the same destination DLCI
	number.
ATM	Consists of an 8-bit virtual path identifier (VPI) and a 16-bit virtual
	circuit identifier (VCI), usually represented in VPI.VCI format, where
	VPI is a decimal number between 0 and 255 and VCI is a decimal
	number between 0 and 65,535. The following is an example of an
	Asynchronous Transfer Mode (ATM) address:
	107.44
	Some vendors’ DSUs require an ATM address that consists of a 0-bit
	VPI and a 10-bit VCI. In this case, the 10-bit VCI maps directly to a
	Frame Relay DLCI.
SMDS	There are two types of Switched Multimegabit Data Service (SMDS)
	addresses: individual addresses, for unicast traffic, and group
	addresses, for multicast traffic. An individual address routes data to
	a unique node. Packets sent to a group address are delivered to all
	nodes that share that address. Both types of address begin with a
	dollar sign. They are distinguished by the first or control digit:
	hexadecimal C for an individual address and hexadecimal E for a
	group address. Each address has 15 decimal digits following the
	control digit and resembles a telephone number. The software
	automatically right-pads shorter addresses with hexadecimal F to
	the full length. The following are examples of individual and group
	SMDS addresses:
	C14085551212FFFF	Individual Address
	E14085551234FFFF	Group Address
X.25	Consists of up to 15 decimal digits and can vary in length. The
	address looks similar to a telephone number and is preceded by a
	pound sign (#). An X.25 address is also referred to as a data
	terminal equipment (DTE) address.

When a device is attached to a public data network (PDN), the network provider assigns it an X.25 address or an international data number (IDN). The first four digits indicate the country and PDN to which the device is attached. The remaining digits represent a unique device address determined by the network provider. The following is an example of an X.25 address:
