Transmit Slip Buffer
Each PRI interface contains “elastic” buffers (also known as Slip buffers) in order to handle situations with different clock frequencies between MGU2 and an external telephony system. Slip buffers are always active in the receive path, but in the transmit path (towards the external system) it is optional to use.
In most scenarios when clock synchronization is properly administrated slip does not occur. However in some (temporary) scenarios, for instance when the DECT sync ring is used for PCM clock distribution there are certain situations when it is preferred to use a free running MGU2 oscillator as PCM sync "master". In such situations to avoid SLIP alarms on “external systems” an activation of a Slip buffer in the transmit path of the E1/T1 Framer of MGU2 is needed.
The activation is made by setting the TX_Slipbuffer parameter.
