Used and Refurbished Juniper E-Series Routers- Broadband Service Routing Platforms
For
carrier-scale multiplay deployments, one of the E-series
application-optimized platforms consists of:
Channelized T3
The line module channelized T3 LM (CT3-12-F0) supports connections
for DS1 and DS0 services over a channelized interface. It also
supports all major private line protocols, including Frame Relay,
PPP, HDLC, multilink PPP and Frame Relay; and scales to support the
aggregation of over 4,000 T1s in a single chassis, and over 12,000
T1s in a single rack.
Channelized OC-3/STM-1 and OC-12/STM-4
The line modules
channelized OC3/STM-1 and OC12/STM-4 (COCX/STMX-F0) provide
optical circuits to the access provider network in support of high
density channelized services. It also supports T3, T1, E1, and DS0
channelization, with support for Frame Relay, PPP, and HDLC.
Fast Ethernet
Fast Ethernet Line Modules (ERX-GEFE-MOD and
ERX-GEFE256M-MOD) support high-speed access facing Ethernet
services. They also support line rate forwarding and value-added
services such as VLAN tagging (802.1Q)
Fast Ethernet/Gigabit Ethernet Combination
The ERX hosts line modules (ERX-GEFE256M-MOD and
ERX-GEFE-MOD). Customers can configure to support either Fast
Ethernet connections to the access network or Gigabit Ethernet
connections to the access or the core network. Both line modules
support line rate forwarding, and provide value-added services such
as VLAN tagging (802.1Q).
Gigabit Ethernet
The ERX supports two Gigabit Ethernet line modules
and provide high-speed Gigabit Ethernet connections to both the
access network and the core networks. The ERX-GE-MOD supports a 2
port Gigabit Ethernet IOA, while the ERX-HDE-MOD supports the 2 port
Gigabit Ethernet IOA and the 8 port high density Gigabit Ethernet
IOA. Both line modules support line rate forwarding, and provide
value-added services such as VLAN tagging (802.1Q).
OC-3/STM-1 and OC-12/STM-4 ATM
The OC-3/STM-1 and OC-12/STM-4 ATM LMs
(ERX-O3O12A-MOD and
ERX-OCXA256M-MOD) support high-speed subscriber access and
high-speed uplink. Full traffic class support, including CBR, as
well as traffic shaping, are supported with on-board, dedicated ATM
packet processors.
OC-3/STM-1 and OC-12/STM-4 and OC-48/STM-16 Packet over Sonet (PoS)
OC-3/STM-1 and OC-12/STM-4 POS LM
(ERX-O3O12P-MOD
and OC3/OC12-POS) support high-speed access network connections and
high-speed uplink into the network infrastructure. The OC48/STM-16 PoS LM (ERX-OC48ST16-MOD) for the ERX-1440 also supports a
high-speed network backbone uplink.
Service Modules
Service LMs (ERX-IPSERV-MOD and ERX-SERVICE-MOD) support highly
scalable L2TP LNS and GRE tunnels, as well as Network Address
Translation (NAT) and Firewall Services. These LMs are internal
systems cards with no associated IOA.
IPSec Service Module
The IPSec Service Modules (ERX-IPSEC-MOD and
ERX-IPSECURE-MOD) encrypt and/or decrypt packets encoded with the
IPSec protocol. IPSec provides secure tunnels between two peers.
