Modify A Interface E1/T1 Timeslot and CIC(MOD AE1T1CIC)

Function

A configuration command that modifies the timeslot type and CIC number of an E1/T1 link on the A interface. In this command, the system uniquely identifies the CIC of an E1/T1 link on the A interface according to Subrack No., Slot No., Port No., and Timeslot No..

Note

1. By default, the timeslot type and CIC number of an E1/T1 link on the A interface are set by running the ADD AE1T1 command.

2. This command applies to only the timeslots with the type of NULL(NULL) or CIC(CIC).

3. The CIC must be different from those configured in the same signaling point group and those configured for the A interface board (E1/T1 mode) to which the same OSP is connected.

Parameters

ID Name Description
SRN Subrack No.

Meaning:Subrack No.

Value range:0~11

Explanation:None.

Default value:None

SN Slot No.

Meaning:Slot No.

Value range:0~27

Explanation:None.

Default value:None

PN Port No.

Meaning:Port No.

Value range:0~83

Explanation:None.

Default value:None

TSN Timeslot No.

Meaning:Timeslot No.

Value range:1~31

Explanation:This parameter indicates the number of the E1 timeslot transmitted on a Ater signaling link over the Ater interface.

Generally, an E1 link has 32 timeslots. Timeslot 0 is specially used for synchronization.

The transmission rate of each timeslot is 64 kbit/s. One timeslot generally consists of eight sub-timeslots (the transmission rate of each sub-timeslot is 8 kbit/s) or four sub-timeslots (the transmission rate of each sub-timeslot is 16 kbit/s).

This parameter cannot be blank.

You can modify the Timeslot No. of only idle E1 timeslots on the same GEIUT or GOIUT.

Default value:None

TSTYPE Timeslot Type

Meaning:Timeslot Type

Value range:CIC(CIC),NULL(NULL)

Explanation:This parameter indicates the function and status of a timeslot. The CIC type indicates a traffic timeslot.

The NULL type indicates that this timeslot is not available.

The Semicon type indicates that this timeslot is a semi-permanent link timeslot.

The SimeTs type indicates that this timeslot is a monitoring timeslot of a BTS.

The ASL type of the A interface indicates that the timeslot is an ASL timeslot, that is, A interface signaling link timeslot (SS7 link timeslot).

The AterOML type of the Ater interface indicates that the timeslot is an Ater OML timeslot.

The AterSL type of the Ater interface indicates that the timeslot is an Ater signaling link timeslot.

The ASL type of the Ater interface indicates that the timeslot is an ASL timeslot. It is used to transmit the signaling (SS7) on the A interface.

The PbSL type of the Pb interface indicates that the timeslot is a Pb signaling timeslot.

The OML type of the Abis interface indicates that the timeslot is an OML timeslot, that is, OML timeslot of the BTS.

The RSL type of the Abis interface indicates that the timeslot is an RSL timeslot, that is, signaling link timeslot of TRXs.

The Sime type of the Abis interface indicates that the timeslot is a Sime timeslot, that is, a monitoring timeslot.

The Idle typeTS of the Abis interface indicates that the timeslot is an idle timeslot,used for testing the interference of the idle channels.

The Chan type of the Abis interface indicates that the timeslot is a traffic channel timeslot of TRXs.

Default value:None

CIC CIC

Meaning:CIC

Value range:0~65535

Explanation:CIC No.

Default value:None

Example

Modify the parameters of an E1/T1 link on the A interface (Subrack No. = 1; Slot No. = 26; Port No. = 0; Timeslot No. = 3; Timeslot Type = CIC(CIC); CIC = 500):
MOD AE1T1CIC: SRN=1, SN=26, PN=0, TSN=3, TSTYPE=CIC, CIC=500;
