Zhone Technologies 800, 900, 600 manual Call Routing

Introduction ACS-PRI/BRI Card

Thus, if local routing is disabled, any call coming into the system on a network side (i.e., local) D channel will be routed only to a user side D channel based on the called number. Even if the called number matches, such a call will never be routed to an HSU port or a network side D channel when local routing is disabled.

If local routing is enabled, then any call coming in on a D channel will be routed to the first matching phone number, regardless of whether or not the match is for a local device.

Figure 6-6shows a system connected to two carriers (A and B), two ISDN PBXs, two video codecs (#1 and #2) and a LAN router. The examples that follow help explain the call routing parameters.

Carrier A	Carrier B
ISDN Switch	ISDN Switch

N

D Channel #1 700-xxx-xxxx

N

D Channel #2 xxx-xxx-xxxx

		IAD
	U	U
U	N	N	U
	D Channel #4		D Channel #3

ISDN PBX #1				ISDN PBX #2
415-940-77xx				800-444-2xxx
	HSU#1	HSU#2	HSU#3

Video Codec #1	Video Codec #2	LAN Router
700-737-2345	700-737-4567	700-737-5511

Figure 6-6. Call Routing

In the example shown in Figure 6-6,the following call routings will occur:

•An incoming call to 700-737-2345 from either carrier will be routed to HSU port #1.

•Any outgoing call from any HSU port will be routed to the D channel specified in the call profile including D channels #3 and #4 to the PBXs.

•A call to 510-623-1574 from the PBX will be routed to carrier B.

•A call to 800-444-2400 from either carrier will be routed to PBX #2.

•A call from either PBX to 700-737-5511 will be routed to HSU #3 if local routing is enabled, but routed to Carrier A if local routing is disabled.
