Vizio EXES-6000 CP-64 operating instructions Group Blocking, Function C

Group Blocking

Function (A)

The system can be grouped or divided into a maximum of 6 groups of stations with consecutive station numbers by exchanges "A", "B" and "C". Different station groups cannot call each another.

[Example 1]

< Exchange	"A" >	Fig. 1	< Exchange "B" >	Fig. 2
	Group 1 No.201~209		Group 1 No.470~479
Group 2	Group 3	Group 4	Group 2	Group 3
No. 210~219	No.220~249	No. 250~279	No.480~489	No.490~499

Tie-line

< Exchange "C" >	Fig. 3
Group 1 No. 740-759
Group 2	Group 3
No. 760~769	No. 770~799

Function (B)-1

The group connected to the same exchange can call and/ or be called by any other group(s) within the same exchange area.

Function (B)-2

Only one pair of groups can call each other across the

tie-lined exchange. The tie-line link of each exchange (4

links) forms a group and like stations.

The groups No.1 through 6 connected to the same

exchange can call exchange by programming in tie-line

links (group No. 7) and (group No. 8).

Explanation of < 3 exchanges tie-lined > (Fig. 6)

1) The		call	can be made from Group No. 2 of exchange
	"A" to tie-line links			of exchange	"A".
2)	Connect tie-line links			of exchange "A" to tie-line
	links		of exchange	"B".
3)	The	call	can be made	from tie-line	links	of ex-

change "B" to group No. 1 of exchange "B".

4)Thus, the call is allowed to go through from Group No.2 of exchange "A" to Group No. 1 of exchange "B".

Function (C)

The paging zone number (All-call, individual zones No.1

~30 for 2 exchanges and No.1 ~ 45 for 3 exchanges) which each group of each exchange can call is program- mable. (No distinction is made between external PA and Station paging.)

Paging to the paging zones of the other exchange is also programmable.

Note.

When the paging call is made, the group of stations to which the response is made is restricted by Function

B.Function B permits the normal station call in the direction of the arrows. Its paging response can be made in the opposite direction of the arrows.

< Example of Paging response >

When the programming is set up for the normal station

call as is shown in Fig. 4, the paging response is only possible in the direction of the arrows of Fig. 8.
