address, plus the data payload and other information. Surrounding a packet is a

frame, which includes information about the transport protocol.

Profile—

A menu (including submenus) that defines a link or system.

Q.931 en-bloc dialing—

A function included in the ISDN User-Network

Interface Layer 3 Specification for Call Control, which has to do with the

messages that are sent over the D channel to set up and disconnect calls.

Remote device or remote end—

Refers to another network. The Pipeline

dials up to or receives calls from a device at the remote end. For telecommuters,

the remote end is the corporate LAN.

Routing—

A method of moving data between your local network and a remote

network. A router requires on-board software that enables it to deliver packets to

a precise network address. Routing has many advantages over bridging, the most

important being that is provides better performance.

Serial WAN port—

The terminal connector on the back of some Pipeline 130

models. When wired for V.35 serial communication, the port supports a high-

speed data connection to your computer from the wide area network.

Tearing down a call—

See clearing a call.

Trunk groups—

Lines that enable the routing of calls between switches. In the

case of IDSL, the DSL service you are attached to over your ISDN line is not part

of the public-switched telephone network (PSTN), but there is a route to the

PSTN over a designated route, which is defined at the central office as a trunk

group. The central office administrator can give you the trunk group number you

need to use to direct out-going voice calls from the IDSL equipment to the PSTN.

User Datagram Protocol (UDP)—

Part of the TCP/IP protocol. It was

designed to provide a way for a packet to get to a particular application, rather

than to a network or a host on a network. UDP uses the IP address and an

additional address, called a port number. The port number for the APP Server

utility is 7001.

When the Pipeline issues a UDP unicast packet to the APP server, it sends a

request to an application on a particular host, since it knows the IP address of the

host, and the port number of the application. If the host doesn’t have a permanent
