DTE Address Structure 195

Examples of DTE Addresses

The following are examples of the DTE Address structures.

Example: SprintNet (Formerly Telenet)

The SprintNet numbering plan is consistent with CCITT Recommendation

X.121 and follows the address structure of a four-digit Data Network

Identification Code (DNIC) followed by a Network Terminal Number (NTN).

A SprintNet network address, which can consist of up to 14 digits, is defined

by the following fixed-length fields:

Data Network Identification Code (4 digits)

The first four digits are the Data Network Identification Code as described

earlier in this appendix.

Area Code Field (3 digits)

This field defines the area code associated with the Called DTE Address, and

functions like a telephone area code.

Server DTE Address Field (5 digits)

This is the address assigned to the particular DTE at subscription time.

Port Field (2 digits)

This is an optional field used by the DTE only and is not interpreted by the

network. For example, it can be used to identify different PCs on a LAN, or a

specific application program. The Port Field must be in the range of 0 through

90 otherwise the network will clear the call.

When making a call within the SprintNet network, the DNIC must be 3110

and the address length must be either 12 or 14 digits. For calls outside

SprintNet, the DTE Address length must be 4 to 14 digits long including the

DNIC.

Example: DATAPAC (Telecom Canada)

DATAPAC local network addresses consist of up to ten digits: an eight-digit

local address plus an optional two-digit sub-address. International addresses

are composed in the following form: 1 + DNIC + NA, where NA is the network

address.
