If the desktop video system supports 1B data, it can make or receive a call using only one B-channel while the MLX telephone is on a call. One B-channel is not generally adequate for video, but some desktop video applications can switch to two channels once the MLX telephone is not on a call.

NOTE:

See‘Desktop‘ Videoconferencing’’ on page 5-33 and ‘‘Group Videoconferencing’’ on page 5-33 for more information about videoconferencing applications.

Ascend Pipeline 25-Px Access Device 3

This communications device requires Release 4.0 or later. It combines the capabilities of an ISDN terminal adapter and a LAN router, allowing high-speed access to Internet services over digital facilities, or permitting a remote user to dial into a main-site LAN server. It allows outgoing calls only. The Pipeline 25-Px connects to the serial port on a PC, to a PC’s network access card, and to an MLX extension jack on the control unit.

The Pipeline 25-Px can use the system’s 2B Data feature when it is programmed for the MLX extension jack. This permits data communications of 112 or 128 kbps, depending upon the digital facility, which must be ISDN PRI or NI-1 BRI. In addition, the Pipeline 25-Px allows Internet and LAN connections at 56 or 64 kbps.

One Pipeline 25-Px is required for each PC, and you cannot connect a phone, fax machine, or other device to the Pipeline 25-Px. To use this device for high-speed Internet access, you must have an ISDN account with an Internet service provider (ISP), as well as client software for browsing, email, and other applications.

NOTE:

For more information about installing and using the Pipeline 25-Px from Ascend Communications, Inc., contact your Lucent Technologies representative and request the MERLIN LEGEND Communications System Application Note, The Internet Connection.
