ProShare(TM) Video: ISDN Q&A
Contents:
1. HOW DOES THE INTEL PROSHARE VIDEO SYSTEM USE THE B AND D CHANNELS?
Voice, video and application data are transmitted and received by the
Intel ProShare Video System using both B channels. The B channels are
not split (application data on one, video on another) but are
essentially like one large data path, which the ProShare Video System
uses to transmit/receive all three types of data.
The D channel is used solely for call setup and management. No
end-to-end user data is transmitted over the D channel.
2. HOW SHOULD MY ISDN LINE BE PROVISIONED SO THAT IT WORKS CORRECTLY WITH THEINTEL PROSHARE VIDEO SYSTEM?
Your ISDN line must be set up according to certain specifications for it
to work properly with the Intel ProShare Video System. Order document
8139: ISDN Provisioning for Intel Blue, for Intel specific ISDN
provisioning information.
3. WHAT IS A SPID?
SPID, or Service Profile IDentifier, is a number issued by your
telephone company. The SPID # is used to identify your ISDN line to the
Central Office switch. The Intel ProShare Video installation software
prompts you for your SPID number, so it is important that you have this
number on hand when installing the product. SPID numbers are provided
by your ISDN service provider (telephone company).
4. WHAT IS AN NT-1 AND HOW DO I USE IT?
NT-1 stands for Network Termination type 1. The NT-1 unit is not
included in the Intel ProShare Video System package; it must be
purchased separately. The NT-1 is a device which converts the two-wire
line (or "U" interface) coming from your telephone company into a 4-wire
line (or "S/T" interface). The NT-1 is physically connected between the
ISDN board of your ProShare Video System and your ISDN phone line. The
NT-1 supports network maintenance functions such as loop testing. Up to
8 terminal devices may be addressed by an NT-1. If your ISDN line is
provided from a PBX as an S/T line, you will not need an NT-1.
For a list of Intel approved NT-1 suppliers, order document 8109.
5. WHY DOES THE INTEL PROSHARE VIDEO SYSTEM USE AN "S/T" INTERFACE INSTEAD OFA "U" INTERFACE?
The "S/T" interface is the ISDN standard for ISDN terminal adapters. In
the case where ISDN service is provided via a PBX, the S/T interface is
often the only interface type required.
6. DOES THE INTEL PROSHARE VIDEO SYSTEM SUPPORT SWITCHED-56?
The Intel ProShare Video System requires Basic Rate ISDN service for
network access; it is not a switched-56 product. However, it will work
through switched-56 networks as long as Basic Rate ISDN service is
available at both end points.
7. DOES THE PROSHARE VIDEO SYSTEM SUPPORT MULTI-POINT PROVISIONING OR MUST MYISDN LINE BE PROVISIONED AS POINT-TO-POINT?
The Intel ProShare Video System supports both multi-point and
point-to-point ISDN provisioning. For more details on Intel specific
ISDN provisioning, order document 8139.
8. DOES THE PROSHARE VIDEO SYSTEM SUPPORT AN ANALOG PHONE?
No, the ProShare Video System does not currently support the use of an
analog phone.
9. CAN MY ISDN PHONE SHARE AN ISDN LINE WITH MY INTEL PROSHARE VIDEO SYSTEM?
At this time, Intel recommends that you maintain a separate line for
your ISDN telephone when in point-to-point mode. In multi-point mode,
the phone can share the line with the ProShare Video System.
