Chapter 3 - Before You Deploy

The PRI direct from the telephone service provider should support both data and voice for Polycom’s voice add-on capability of systems.

Determining Usage

To get the best rate of return from PRI lines, they should be used as much as possible. To do this, look at the data and video traffic as a whole. Establish a reasonable ratio between the total bandwidth required if every device is in use and the number of lines provided. A ratio of 10:1 is fair for general use. If you use a PBX, access switch, or other data communications unit, the total number of lines into your customer premise equipment (CPE) can be allocated by channel to your equipment, according to the bandwidth required at any given time.

PBX Network Configuration

The PBX or other CPE that will be providing the ISDN PRI interface to the system must be able to provide a clock signal.

Other than the clocking requirement, the rest of the ISDN PRI provisioning on the PBX is very similar to what would be requested of an outside ISDN provider.

ISDN BRI

All Polycom ISDN BRI interfaces are S/T-loop. ISDN BRI lines coming direct from a Telco are U-loop, so if your system is not behind a PBX or other private network, you must connect the BRI interface to BRI line(s) through an NT1 device capable of supporting multiple BRI lines.

NT1 Devices that you may order through Polycom:

❑Single NT1 (2200-08406-001 or NT1)

❑Triple NT1 (2200-08406-003)

❑Quad NT1 (2200-08406-004 or NT1-QUAD)
