2-way DID

With PRI the same lines can be used for receiving direct inward dialing (DID) and

for making direct outward dialing (DOD) calls.

The dialing plan configured by your customer service representative determines

how calls are routed. Consult your customer service representative to determine

whether or not this feature is compatible with your service provider.

Dialing Plan and PRI

The Dialing Plan supports PRI connectivity to public and private networks. The

dialing plan is a collection of features responsible for processing and routing

incoming and outgoing calls. All PRI calls must go through a dialing plan.

The Dialing Plan

• allows incoming calls to be routed to sets based on service type and digits

received

• provides the ability to map user-dialed digits to a service type on a Call by Call

basis

• allows long distance carrier selection through user-dialed Carrier Access Codes

Consult your customer service representative to determine how your dialing plan is

configured.

ISDN hardware

To support connections to an ISDN network and ISDN terminal equipment, your

Enterprise Edge must be equipped with a BRI S/T Media Bay Module (EE-BRIM

S/T) or a Digital Trunk Media Bay Module (EE-DTM) card configured for PRI.

PRI hardware

The Digital Trunk Media Bay Module (EE-DTM) is configured for PRI. In most

PRI network configurations, you need one EE-DTM configured as PRI to act as the

primary clock reference. The only time when you may not have an EE-DTM

designatedas thePRIprimary clockreferenceis in anetwork where your Enterprise

Edge system is connected back-to-back with another switch using a PRI link. If the

otherswitchisloop-timedtoyourEnterprise Edgesystem, yourEE-DTM (PRI) can

be designated as a timing master.

If your Enterprise Edge has more than one EE-DTM configured as PRI, you must

assign the first EE-DTM as the primary reference, the second EE-DTM as the

secondary reference, and the third EE-DTM as the timing master.
