2.6. Gigabit Switch
Migration towards IP is the future trend of network development.
MSAP2000 has incorporated the Optical Gigabit Ethernet (GbE)
Module, to elevate its optical trunking to 1000 Mbps bandwidth.
GbE’s built-in L2 Switch functions will support new broadband IP
services.
Layer 2 Switch
Functions
The Ethernet Switch Module (ESM) supports 8 10/100 Mbps
Ethernet interfaces, and provides Packet Switch functions, such
as IEEE802.1d STP, 8021p, Port-based & tag-based VLAN, and
Static MAC address filtering.
AAM +
Optical Gigabit
Ethernet
The GbE Module supports 16 x 100/1000BaseT Ethernet Links,
and can connect to the AAM Module using the backplane high
speed bus, to form a complete IP DSLAM structure. This module
can support up to 192 lines of ADSL2/2+.
