TDM-TDM

Connects TDM-to-TDM

TDM-to-TDM E1/T1 connections are so-called by the TDM Cross-Connects or TDM Native Bridging are fully supported by the RtpBridge engine. It is possible to crossconnect an individual E1/T1 timeslots to any arbitrary outgoing TX E1/T1 timeslot on arbitrary E1/T1 span. To do that a generic Command CONNECT is used. As an additoonal feature it is possible to convert G.711 A-law->u-law in the cross-connect.

Command syntax Description

connect tdm:li<E1T1_span_in>:ts<timeslot_in>[:codecTDM_in] tdm:li<E1T1_span_out>:ts<timeslot_out>[:codecTDM_out]

Fields:

RX Part (TDM E1/T1) - the data is taken from:

E1T1_span_in - E1/T1 Span Number, from 0 ... N-1, N=2 for the Alvis-CSI-2 or N=4 for the Alvis-CSI-4

timeslot_in - TDM E1/T1 Timeslot Number, 0 ... 31

codecTDM_in - Codec to be used for the TX to the E1/T1 timeslot. Default is g711a. Options: g711a,g711u,slin.

TX Part (TDM E1/T1) - the data will goint to:

E1T1_span_out - E1/T1 Span Number, from 0 ... N-1, N=2 for the Alvis-CSI-2 or N=4 for the Alvis-CSI-4

timeslot_out - TDM E1/T1 Timeslot Number, 0 ... 31

codecTDM_out - Codec to be used for the TX to the E1/T1 timeslot. Default is g711a. Options: g711a,g711u,slin.

TDM-TDM E1/T1 Crossconnect examples

TDM-TDM Example: Sending to another span

   connect tdm:li0:ts1:g711a tdm:li1:ts1:g711a

In this example a data from E1/T1 timeslot 0 span 1 will go to the span 1 timeslot 1, the same codec G.711 A-law.

TDM-TDM Example: Loopback to the same span

   connect tdm:li0:ts1:g711a tdm:li0:ts1:g711a

In this example a data from E1/T1 timeslot 0 span 1 will return the the same the span 0 timeslot 1, the same codec G.711 A-law.

TDM-TDM Example: Changing codec to the same span

   connect tdm:li0:ts1:g711a tdm:li0:ts1:g711u

In this example a data from E1/T1 timeslot 0 span 1 will return the the same the span 0 timeslot 1, the transcoding is made a-law->u-law G.711.
