Great News
Hi,
This morning, I passed successfully my CCIE Voice written exam … I’m feeling well now and will take some rest before to go ahead very soon with the lab portion.
What a good news …. 🙂
Last day before the target
Urgh 🙂 it is the last day before the exam …. Tomorrow at this time , I will be sitting in the exam room.
As usual I’m feeling that I’m missing some points but I’m on the starting blocks to do my final study day.
The best I can do is to continue for tomorrow and all this study is not lost as It will serve for another day if I need but is also very helpful for the OEQ .

Modem Relay / Modem Pass-through
As for fax-relay, the gateway demodulates the signal sent by the modem and send it over IP network by using the Simple Packet Relay Transport (SPRT) protocol. The remote gateway process it at the reverse side.
Modem pass-through is similar to pass-through as everything is sent in-band.
Store-and-forward Fax
Store-and-forward fax on IP networks operates like email and so can deliver to servers or remote fax.
T37 is the ITU standard for store-and-forward fax transmissions.So a fax is converted into a TIFF attachment and sent to the network (it is the onramp gateway).Then the TIFF is sent to a server or an offramp gateway.
