First ISDN deployment over new OCTOI TDMoIP protocol
First successfuly wide-area deployment of Osmocom efficient TDMoIP protocol for OCTOI network.
Yesterday, laforge and manawyrm have managed to establish the first successful calls between two ISDN PBX interconnected via the Proposed_efficient_TDMoIP protocol implemented in osmo-e1d using the icE1usb hardware.
The setup looks as follows:
Using this setup we could validate so far:
- the new, efficient and transparent OCTOI TDMoIP protocol works over public consumer internet access (VDSL on one end / DOCSIS on another end)
- GPS-locked oscillators on both sides provide stable shared clock for cycle-slip free operation
Contrary to other established TDMoIP protocols, it is both transparent / protocol-agnostic and only transmits those timeslots of a E1 PRI circuit that are in use.
We are therefore fairly certain that this setup can be the basis of the larger intended Community_TDMSS7_Network we have in mind. There is lots of work to do, and we appreciate any help (see project issue tracker).
