Number of Bytes Sent over an IPPM Link

Measurement Counter

L01025:IPPM_BYTES_TX

Description

This measurement provides the number of bytes sent from the BSC to the BTS over an IPPM link in a granularity period.

NOTE:

In Abis over IP mode, one service connection between the BSC and the BTS is mapped onto one IPPM link. Four types of IPPM services are supported: CS voice, CS data, PS HighPRI, and PS LowPRI. The signaling connection between the BSC and the BTS is not mapped onto any IPPM link.

Unit

byte.

Measurement Point

The counter is measured on the BSC side, as shown in Figure 1.

Figure 1 IPPM performance measurement point

The IPPM link is established between the IP interface board in the BSC and the IP interface board in the BTS. When the BSC communicates with the BTS, the IPPM link starts to send the data. The counter is used to measure the number of bytes sent over an IPPM link.

Formula

This is an original counter without involving any formula.
