2. Central office switch
● Digital access switch equipment attached to or
inside a router calls the central office switch.
Other circuit-switched services use standard
dialing tones.
3. ● The dial-up router recognizes data with a
destination outside the LAN and initiates a call
to a destination selected from a preprogrammed
table.
4. Central office
● The central office of local telephone company
is a computerized switch that works with other
similar switches to route and complete a call .
● A switching matrix connects local access lines
and long distance server on a temporary per-
call basis.
5. ● A high-speed intraswitch trunk is a fiber-optic
link operating at a minimum of 45 megabits per
second.
● The origination router strips off the Ethernet data
and send s TCP/IP packets across the LAN-to-
LAN connection, packages the TCP/IP packets
into Ethernet.
● Client devices on each LAN can access servers
and services on the other network, but with
reduced speed.
