ISDN/PSTN Network Services<br />

<strong>Polycom</strong> <strong>RMX</strong> <strong>2000</strong>/4000 Administrator’s <strong>Guide</strong><br />

To enable ISDN and PSTN participants to connect to the MCU, an ISDN/<br />

PSTN Network Service must be defined. A maximum of two ISDN/PSTN<br />

Network Services, of the same Span Type (E1 or T1) can be defined for the<br />

<strong>RMX</strong>. Each Network Service can attach spans from either or both cards.<br />

Most of the parameters of the first ISDN/PSTN Network Service are<br />

configured in the Fast Configuration Wizard, which runs automatically if an<br />

RTM ISDN card is detected in the <strong>RMX</strong> during first time power-up. For<br />

more information, see the <strong>RMX</strong> <strong>2000</strong> Getting Started <strong>Guide</strong>, "Procedure 3:<br />

First-time Power-up and Connection to MCU” on page 2-9.<br />
