Groups cannot call each another | TOA Electronics CP-66 guide

Group Blocking

Funtion (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).

[Example 2-2]	< 2 exchanges tie-lined >		Fig. 5
	< 2 exchanges tie-lined >		Fig. 5

< 3 exchanges tie-lined > Fig. 6

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.

(Refer to Fig. 4 and Fig. 8)

possible in the direction of the arrows of Fig. 8.
