Overview
WireSpan 600 is a cost-effective, single-port fractional E1 access unit.
The fractional E1 service makes unused time slots on long-range E1
trunks available for other users.
WireSpan 600 provides a synchronous data channel that supports
user-selectable transmission rates. The available data rates are integer
multiples of 64 kbps; the multiples range is 1 through 32, corresponding to
a maximum of 2048 kbps. The user’s payload data is packed in the
corresponding number of time slot of an E1 (CEPT 2.048 Mbps) data
stream, for transmission over public or private E1 networks.
