- -------------------------------------------------------------------------------
-
- Three basic types of coin services are available: semi-postpay, prepay, and
- local repay toll postpay.
-
- A] Semipostpay Coin Service.
- =-=-=-=-=-=-=-=-=-=-=-=-=-=-
- 1) When the telephone receiver is removed from the payphone, dail tone is
- returned to the caller. After the telephone user completed dialing and the
- connection to the called line is established, the telephone user listens to
- determine when the call is answered. Upon answer, the transmitter in the pay
- phone is disabled and coversation is inhibited. The phone user must then
- depoit a coin to enable the transmitter, thereby permitting conversation. Once
- a coin has been deposited, it cannot be returned.
-
- 2) On calles from semipostpay coin lines to the operator, a special
- paystation identification tone is given to the operator on answer. (This tone
- is controled by class-of-service assignment.) If supervision is not given,
- conversation is allowed on calles to the operator as well as other lines with a
- free terminating class of service.
-
- 3) Semipostpay coin service requires no special DCO system equipment, and
- operator rering capability is permitted.
-
- B] Prepay Coin Service.
- =-=-=-=-=-=-=-=-=-=-=-=
-
- 1) Prepay coin sevice provides coin collect, coin return, and rering
- capability (GREEN BOX). The DCO system does not require special prepay trunks
- or trunk groups.
-
- 2) On local calls, coins are automatically collected on completeted calls and
- returned on incompleted calls. On toll calls, the operator has *FULL* control
- of coin collect, coin return, and rering functions. Any coin not returned by
- the operator will be collected on disconect.
-
- 3) Two basic methods are used for operator control of paystations in the DCO
- system: inband signaling and multiwink signaling. For inband signaling, coin
- collect, refund, and rering functions are controlled by MF signals applied to
- the voice path. For multiwink signaling, coin collect and refund signals are
- controlled by a series of up to five supervisory winks (momentary on-hook
- signals). (See following chart for inband and multiwink signaling
- arrangments.)
-
- 4) A + or - 130volt power supply is required for prepay station operation to
- provide coin collect and coin refund voltages. In addition, certain types of
- paystation instruments also require a +48volt supply.

- C] Local Prepay/Toll Postpay Service
- =-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=
-
- 1) Prepay line circuits and circuit unit assemblies are required for coin
- collect and refund on local calls. Local prepay service requires a coin
- deposit before dialing can proceed. On local calls, coins are automatically
- collected when the called party answeres. On toll calls, the initial deposit
- is returned before the operator answers.
-
- 2) Answer provides reverse battery supervision, which locks the coin
- mechanism of the payphone in the collect position. Deposits made on operator
- instruction are not refundable.
-
- Coin Service, Prepay Coin on DSU-Remote (DSUR).
- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-
- Prepay coin service for the DSUR is accomplished in the same fashion as in
- the DCO system. A maximum of prepay paystations are allowed per DSUR. (See
- the apove chart for inband and multiwink signaling arrangements.)
