(a) Right Group with H.Q. at MARIE JEAN FARM, will establish a forward exchange at B.12.c.5.3. (present H.Q. 5th Army Field Bde.).
Three Trunk lines, of which two will be ringing and one buzzer call, will be connected from Group H.Q. to this forward Exchange. These lines will be in the buried system as far as B.12.d.80.85.
Lines to Batteries will be laid overground from the Forward Exchange. Most of these lines already exist, and the general scheme should be similar to that shown on the diagram.

(b) Left Group with H.Q. at MARGUERITE FARM will establish a forward exchange at B.6.c.3.3. (present H.Q. of 75th Bde R.F.A.).

Lines to Batteries will be laid overground on the principle shown on attached diagram. Some of these lines already exist.

(c) In each case, the buzzer line from Group to Forward Exchange will be used for transmission of messages by Fullerphone.
Any message containing information which might be useful to the enemy will be sent on from Forward Exchange to Batteries by runner.

Communication between Group H.Q. and any battery in the group may be established, but orders applying to several, or all the batteries in the group should be sent to the Officer i/c Forward Exchange for transmission. This applies to S.O.S. originating at Group H.Q.

3. PERSONNEL AND MAINTENANCE.
All connections in the buried system and maintenance between Group H.Q. and their Forward Exchanges will be taken charge of by D.A. Signals.
Each group must arrange to provide telephonists for the Group H.Q. Exchange and their Forward Exchange. A sufficient number of linesmen must be posted at the Forward Exchange to maintain lines to batteries.

4. SEALED PACKETS.

For Motor Cyclist Despatch Rider runs, see attached list, which is subject to revision.
