are available only for lab testing purposes.

 Combo eWAG + TTG deployment on the same ASR 5000 chassis.

 Combo eWAG + TTG + GGSN deployment on the same ASR 5000 chassis.

Important:

and Limitations

The Gn' reference point is located between the eWAG and the GGSN supporting GTPv1 and GTPv0 protocols. eWAG

supports GTP Path messages towards GGSN. Here, the eWAG acts as an SGSN and initiates the PDP Context Creation

procedure. For every UE, the eWAG creates one GTP tunnel with the GGSN. The UE's APN and IMSI are forwarded

to the GGSN in the Create PDP Context Request message. This APN is either the subscribed APN from the HLR for the

connecting user, or the locally configured default APN at the eWAG.
