PRI networking using Call-by-Call Services

This example highlights the use of PRI Call-by-Call Services. It shows two offices

of a company, one in New York and one in Toronto. Each office is equipped with

an Enterprise Edge 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 to

allow for a coordinated dialing plan between the offices, private lines are used to

handle inter-office traffic.-

PRI networking using Call-byCall Services

If call-by-call services were not used, each Enterprise Edge system might have to

be equipped with the following trunks:

• 12 T1 DID lines needed to handle peak incoming call traffic.

• 8 T1 E&M lines needed to handle inter-office calls.

• 8 lines needed to handle outgoing public calls

The total required is thus 28 lines. If the Enterprise Edge systems were using T1

trunks, then two T1 spans would be required at each office. Note that the total of 28

lines represents the worst case value for line usage. In reality, the total number of

lines in use at any one time will generally be less than 28. For example, during

periods of peak incoming call traffic, the demand for outgoing lines will be low.

With PRI call-by-call services, it is not necessary to configure a fixed allocation of

trunks. Each of the 23 lines on the PRIcan be used for DID, private Tie, or outgoing

public calls. This consolidation means that it may be possible for each office to use

a single PRI span, rather than two T1 spans.With PRI call-by-call services, the only

limitation is that there are no more than 23 calls in progress at any one time.
