`
`5.5.3.l.5 Reggest Emergency Call Message, RQE
`
`This message is transmitted to the TSC by a radio unit requesting an
`emergency call.
`The RQE codeword contains all the information necessary to
`request a call to a unit or group of units with the same prefix,
`to all
`units in the system,
`to a prearranged PSTN destination or to a PABX
`extension that can be accommodated in the range 0-8191.
`In addition, RQE
`may be used to request entry into the extended addressing mode for an
`interprefix call, a general call to the PSTN or a call to a PABX extension
`with a "long" number.
`See section 10 for the emergency call procedures.
`
`RQE may also be used to request a special mode of service previously
`arranged with the system.
`
`Usually emergency calls will take precedence over all other calls.
`Emergency calls may be pre-emptive,
`that is, another call may be terminated
`prematurely to free a channel for an emergency call.

`
`This message is transmitted on a control channel by the TSC as
`follows.
`
`a.
`
`b.
`
`c.
`
`It may be transmitted to a called radio unit to establish the
`availability of the called unit/user prior to allocating a traffic
`channel for a call
`(see 9.1.1.5), or prior to including a unit in an
`existing call (see 11.1.5).
`
`It may be sent to check the availability of a called radio unit before
`the TSC transmits a short data message (HEAD); see 14.1.6.
`
`It may be sent to a requesting radio unit to check that it is still in
`radio Contact and to restart its waiting timer (see, for example,
`sections 8.2.1.3, 9.1.1.7 and 9.1.1.10).
`
`AHY may also be sent by the TSC to a radio unit on a traffic channel,
`for example to check that the unit has reached, or is still on,
`the channel
`(see 6.1.2.1 and 9.1.2.2), or to restart the waiting timer of a radio unit
`which has requested an Include call
`(see 11.1.7).
`
`to
`one data codeword may be appended to the AHY address codeword,
`convey additional information, depending on the value of bit AD.
`(In this
`issue of the standard, this facility is used only when the AHY is sent on a
`control channel to a called radio unit).
`
`AHY demands an acknowledgement
`
`from the addressed unit:
`
`i)
`
`For AD
`
`'0'
`
`the addressed unit responds in
`- On a control channel,
`the slot following the AHY.
`On a traffic channel,
`the unit times its response
`from the end of the AHY address codeword.

`
`I
`
`the addressed unit responds in

`codeword].
`On a traffic channel,
`the unit times its
`response from the end of the data codeword.

`
`5.5.3.2.? Status Aho Messa e
`
`AHY
`
`This message is transmitted on a control channel by a TSC to inform a
`called radio unit of status information sent by a radio or line unit.
`For
`an interprefix status message,
`IDENT2 in the AHYQ address codeword is set
`to IPFIXI and a data codeword is appended containing the calling unit's
`address.
`AHYQ is also used to send a S—bit status message to a radio unit
`from the TSC.
`
`AHYQ demands an response ACK, ACKX, ACKV or ACKB from the called unit
`(i.e. the unit whose individual address is PFIX/IDENT1):
`
`-
`
`-
`
`in the slot following the AHYQ address codeword, for a
`common-prefix status message (IDENT2 = ident) or a message
`from the TSC (IDENT2 = TSCI);
`in the slot following the appended data codeword, for an
`interprefix status message (IDENT2 = IPFIXI).

`
`5.S.3.2.8 Short Data Invitation Message, AHYC
`
`This message is used by the TSC to instruct a radio unit to send a
`short data transmission (see sections 9.2.2.1, 11.3.1 and 15.2).
`
`AHYC is used in two Modes:
`
`-
`
`-
`
`In Mode 1, AHYC instructs a calling radio unit to send addressing
`information (see SAMIS, section S.6.l.2.2) or RQC data (see HERD,
`section 5.6.2), when a preceding request message from the radio
`unit has indicated the requirement.
`Mode 1 is distinguished by
`setting PFIX/IDENT2 to a radio unit's individual address.
`
`In Mode 2, AHYC demands that a radio unit transmits a data message
`of a prescribed type (see section 15);
`for example,
`the TSC may
`demand the serial number of a radio unit.
`It is an interrogation
`mode, not part of a call requested by the radio unit. Mode 2 is
`distinguished by setting PFIX/IDENT1 to a radio unit's individual
`address (with IDENT2 as a non-radio-unit ident).
`
`The type of data to be transmitted by the radio unit is indicated by
`the DESC field and the non—radio-unit ident: the meaning of DESC can be
`different for the two modes.
`
`AHYC may be sent on either a control channel or a traffic channel.

`5.5.4.1 Control Channel Marker, MARK
`
`This message may be transmitted on a control channel by a TSC. For
`example, it may be sent as the first address codeword(s) on a newly
`designated control channel
`in order to accelerate control channel
`acquisition by radio units (see 3.3.3.1).
`It does not need an address
`PFIX/IDENTl, so bits 2-21 are reused.
`
`The message fields A and B are chosen so that:
`
`i)
`
`the parity check bits always form the control channel codeword
`synchronisation sequence, SYNC (see section 3.2.1.1), and
`
`ii)
`
`the number of bit transitions included between bits 33 and 49 is the
`maximum achievable,
`taking into account condition i) above.
`The bit
`values of these fields will depend on CHAN4 and the system identity
`code.
