3GPP TS 27.007 V6.3.0 (2003-

06)

Release 6

Test command returns values supported as a compound value. If MT/TA supports several RLP versions <verx>, the

RLP parameter value ranges for each <verx> are returned in a separate line.

Defined values

<ver>, <verx>: RLP version number in integer format; when version indication is not present it shall equal 0

NOTE 2: Versions 0 and 1 share the same parameter set. Read and test commands shall return only one line for this

set (where <verx> is not present).

<iws>, <mws>, <T1>, <N2>, <T4>: IWF to MS window size, MS to IWF window size, acknowledgement timer

T1, retransmission attempts N2, re-sequencing period T4 in integer format (default values and value ranges

depend on RLP version; refer 3GPP TS 24.022 [18]): T1 and T4 are in units of 10 ms.

Implementation

Mandatory when RLP implemented.

6.9 Service reporting control +CR

Table 16: +CR parameter command syntax

Command

Possible response(s)

+CR=[<mode>]

+CR?

+CR: <mode>

+CR=?

+CR: (list of supported <mode>s)

Description

Set command controls whether or not intermediate result code +CR: <serv> is returned from the TA to the TE. If

enabled, the intermediate result code is transmitted at the point during connect negotiation at which the TA has

determined which speed and quality of service will be used, before any error control or data compression reports are

transmitted, and before the intermediate result code CONNECT is transmitted.

NOTE: This command replaces V.250 [14] command Modulation Reporting Control +MR, which is not

appropriate for use in the GSM/UMTS network. Possible error control (other than radio link protocol) and

data compression reporting can be enabled with V.250 commands Error Control Reporting +ER and Data

Compression Reporting +DR.

Test command returns values supported as a compound value.

Defined values

<mode>:

disables reporting

1 enables reporting

<serv>:

ASYNC asynchronous transparent

SYNC synchronous transparent

REL ASYNC asynchronous non-transparent

REL SYNC synchronous non-transparent

GPRS [<L2P>] GPRS

The optional <L2P> proposes a layer 2 protocol to use between the MT and the TE. It is defined in the Enter GPRS

Data Mode (+CGDATA) command.
