In the above example:
If a user in New York calls Toronto within the network, they 
dial 6221. The local Norstar checks the number against the 
routing tables and routes the call according to the destination 
code 6, which places the call using Route 001. 
There is no DialOut change to the number from New York, so 
the call appears on the auto answer line on the Norstar in Santa 
Clara as 6-221. 
Because 6 is also a destination code on the...

Dialing plans with shared line pools
Using routes and destination codes is a powerful and efficient 
way to create a transparent dialing plan. Line pools offer an 
alternate method of creating a dialing plan or supplementing 
the routing and destination codes. This is the type of dialing 
plan you would create for tandem networking between two or 
more Norstar systems.
If the Norstar systems are close to each other geographically, 
you can...

Networking with shared line pools
For instance, the person on system A at telephone 234 can 
press an Intercom button and dial 7434. 
This means that telephone 234 has dialed the line pool access 
code of the trunk to system C, and will receive the dial tone of 
system C. The digits 434 then map to the Received number 
434, and ring telephone 434 with an appearance of the 
associated target line.

Call-by-Call Services Example
This example highlights the use of PRI Call-by-Call Services.
It shows two offices of a company. One office is in New York, 
the other is in Toronto. Each office is equipped with a Norstar 
system and a PRI line. Each office has to handle incoming and 
outgoing calls to the public network. In addition, employees at 
each office often have to call colleagues in the other office. To 
reduce long-distance costs, and...

Call-by-Call routing
If call-by-call services were not used, each Norstar system 
might have to be equipped with the following trunks:
12 DID lines needed to handle peak incoming call traffic.
eight Tie (E&M) lines needed to handle inter-office calls.
eight lines needed to handle outgoing public calls
The total required is 28 lines. If the Norstar systems were using 
T1 trunks, then two T1 spans would be required at each office. 
Note...

With PRI call-by-call services, the only limitation is that there 
are no more than 23 calls in progress at any one time.
The dialing plan at each Norstar site is configured to determine 
the call type based on the digits dialed by the user. If a user in 
Toronto wishes to dial a colleague in New York, they dial the 
four-digit private DN (such as 6221). The dialing plan 
recognizes this as a private network DN, and routes the call 
using Tie...

PRI dialing plan example for two-way DID
The following list shows the steps involved in configuring a 
dialing plan for two-way DID which uses a Public service. In 
this example the user dials the prefix 8 to place a call over a 
PRI line. 
Note:  Call-by-call is not needed to have two-way DID.

Private networking using PRI SL-1
You can use PRI SL-1 lines to tandem a number of Norstar 
units into a private network. This creates a Private Network 
Tandem Calling (PNTC) configuration. Refer to Private 
Network Tandem calling on page 112.
You can also use PRI SL-1 lines to link one or more Norstar 
systems to a Meridian 1 system, or to create a network that 
includes one or more Business Communications Manager...
