132 / Private networking using PRI SL-1 Modular ICS 6.1 Installer GuideP0603534 02 Additional Configuration In this example, outgoing public network calls dialed from a Norstar telephone are passed to the Meridian 1, and the Meridian 1 is responsible for seizing a public trunk. For this reason, the 9 prefix is left in the number passed to the Meridian 1. This necessitates modifying the Public DN lengths table on each Norstar to account for the extra leading digit. Essentially, the eight pre-configured entries are modified to include a leading 9 in the prefix digits, and the length value for each entry is increased by one. The new entries are listed below. Carrier codes: If a system has a different long-distance service from the local service, or if the long-distance service changes within the schedules, the routing tables can be set up to include a carrier code. You define the code under System Programming/ Access codes/Carrier codes. You then refer this to the routing tables in Services/Routing Service/route/ Prefix Length Default 8 90 12 900 13 901 18 9011 19 91 12 9411 4 9911 4

Meridian M1 Configuration: • Meridian M1 is the timing master for the private network PRI connections. • Meridian M1 uses descending mode for PRI B-channel selection. • The Meridian M1 must recognize calls dialed to 2xxx and 6xxx numbers, and route the call over PRI to either the East or West end offices. The same applies to incoming DID calls from the public network. • The Meridian M1 must recognize numbers starting with 9 as public numbers, whether the numbers are dialed by Meridian M1 users or by Norstar users.
134 / Private networking using PRI SL-1 Modular ICS 6.1 Installer GuideP0603534 02 MCDN Private Networking When you use MCDN on your private network, you gain the advantages of being able to use a central voice mail/Auto Attendant system to service the entire network, as well as gaining advanced system network features, which keep network traffic flowing along the most efficient paths. MCDN networking uses PRI SL-1 lines and the MCDN protocol firmware. You need keycodes for each of these features. To set up calling over an MCDN network, you define a dialing plan that allows the user on any system to experience consistent dialing strings for internal and external calls. For this type of network, the DNs need to be the same length, but they do not have to be unique to the entire network. If your network is connected to a Meridian 1, and it is the Meridian that you are using for centralized voice mail and Auto Attendant, you can use either a UDP or CDP dialing plan. • If you use UDP, you dial a unique location code with the local telephone DN range. • In the case of CDP, the first digit of the DN range denotes the node and is unique to each system. However, if you are using a Norstar voice mail/Auto Attendant for your centralized voice mail, you must create the calling protocols on the network using CDP. This is a private dialing plan where the first digit of the extensions for each system is unique to that system, and all DNs on all systems are the same length.
