T8110L H.100/H.110 Switch
1 Introduction
The T8110L is the newest addition to the
Ambassa-
dor
series of TDM switching and backlane intercon-
nect standard products. The T8110L can switch 4096
simultaneous time slots with 32 bidirectional local
streams and 32 bidirectional H.100/H.110 streams.
The T8110L has all the features of the T810X
devices. Additionally, the T8110L has more robust
clocking fallback abilities and is pin compatible with
the T8110. (The full version of the T8110 has a PCI
and minbridge interface.)
