Network Interfaces Available on the Passport 5430
Network Interface
Description
Ethernet and
Second Ethernet
Supports the Ethernet and IEEE 802.3 standards that provide LAN connectivity. The
Passport 5430 can have one or two Ethernet interfaces on the system processor
card.
The Ethernet interface on the system processor card is a 10/100BASE-TX. The
10/100BASE-TX interfaces provide unshielded twisted pair (UTP) support.
Serial
Each port can operate independently with RS-232, RS-422, RS-449, RS-530, V.28,
V.35, and X.21 cables. Serial capability allows internal or external clocking.
ISDN BRI
Supports an S/T or U interface. The BRI provides two B channels and supports full
D-channel signaling and call setup/teardown as defined in 1988 CCITT (now ITU-T)
Q.921 and Q.931. For more information about ISDN, functional groups, or reference
points, see
Configuring Dial Services.
The ISDN BRI option is available as an adapter module for any Passport 5430 model.
FT1/T1 and
FE1/E1 DSU/CSU
Provides an interface to convert incoming packet data from an external T1 or E1 line
(using an RJ-48C connector). Because the interface integrates the channel service
unit (CSU) function on each T1 or E1 port, it allows direct connection to the network.
A T1 or E1 port can transmit or receive one HDLC channel for each DS1 or E1 frame
that is configured as Nx DSO speed up to a span of 24 (T1) or 30 (E1) DSO
channels.
ATM T1/E1
Provides a T1 or E1 interface for ATM WAN services.
Dual synchronous
Provides data terminal structured circuit emulation service (CES) over the ATM WAN.
Each port can operate independently with V.35, and X.21 cables. Each port is
synchronized to the Passport 5430 backplane.
V.34 modem
Provides a V.34 modem interface (North America only).
