How are T1 and E1 systems linked for international communication?

[magnetra]

USA uses T1 digital hierarchy where as Europe uses E1 hierarchy. How are two systems linked for international communication?

what is bz8s hdb3

for instant devices: Rad Data Communications DXC-2

T1 - E1

Could you be a little more descriptive?

Re: T1 - E1

most important in converter is- control of buffer because devices in the both sides wants fluxation in this same real time, clock gives several possibility of tacts, there must be change code from HDB3 to AMI, change framing G.704 to D4, impedance etc.

T1 - E1

Similar to the North American T-1, E1 is the European format for digital transmission.
E1 carries signals at 2 Mbps (32 channels at 64Kbps, with 2 channels reserved for signaling and controlling), versus the T1, which carries signals at 1.544 Mbps (24 channels at 64Kbps). E1 and T1 lines may be interconnected for international use.

T1 - E1

e1 has 32 time slot and t1 has 24 but they frames repeat each 125 us so with buffering chaneg them
of cource coding of linr from hdb3 chang to bz8s too

Long haul transport will use Fiber Optics.
