Automatic Protection Switch
The automatic protection switch (APS)
enables route protection on E1 level.
If used, the Alcatel-Lucent 1511 BA
transmits data via two different E1
routes. At the receive side, data coming
from the preferred route is used; if this
route fails, data is taken from the
other side.
Ethernet Switching
On an E1 trail across multiple Alcatel-
Lucent 1511 BA multiplexers, a group
of 64-kb timeslots (N: 1...31) is reserved
to carry Ethernet frames. In each Alcatel-
Lucent 1511 BA, one 10/100Base-T LAN
board (LANtrib) can drop/insert its local
Ethernet traffic onto these reserved
timeslots. To connect multiple Ethernet-
based end devices, the LANtrib offers
five external RJ-45 interfaces. The
LANtrib also switches LANs across mul-
tiple and distinct Alcatel-Lucent 1511
BA multiplexers. Switching between
the local five Ethernet ports runs at
wire speed.
