JunosE 11.2.x Physical Layer Configuration Guide
ES2 4G Line Module
78
NOTE: The OC3-2 GE APS I/O module does not support APS in the current release.
The E120 and E320 routers support the ES2 4G LM. Other E Series routers do not support
the ES2 4G LM. For more information about modules on the E120 and E320 routers, see
the E120 and E320 Module Guide.
The ES2 4G LM supports IOAs that support single-mode operation (intermediate reach
or long haul). IOAs are available in a halfheight size, which enables you to configure them
in either of the two IOA bays that are available for each slot. For more information about
installing IOAs, see the E120 and E320 Hardware Guide.
In the current release, the ES2 4G LM pairs with IOAs to provide OCx/STMx ATM,
OCx/STMx POS, Gigabit Ethernet, 10-Gigabit Ethernet, and tunnelservice interfaces.
NOTE: For more information about configuring a Gigabit Ethernet interface or 10-Gigabit
Ethernet interface, see "Configuring Ethernet Interfaces" on page 167.
For more information about configuring a tunnel-service interface by using the Tunnel
Server IOA, see "Managing Tunnel-Service and IPSec-Service Interfaces" on page 207.
E120 Router Configuration
The 120 Gbps switch fabric of the E120 router allocates 10 Gbps of overall bandwidth to
each line module slot. The line interface on the ES2 4G LM when installed in a 120 Gbps
fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes from
64–1518 bytes or a mixture of packet sizes that represent Internet mix traffic (IMIX).
E320 Router Configuration
The 100 Gbps switch fabric of the E320 router allocates 3.4 Gbps of overall bandwidth
to each regular line module slot and 10 Gbps of overall bandwidth to each of the turbo
slots (slots 2 and 4). The line interface on the ES2 4G LM when installed in a 100 Gbps
fabric configuration is 3.4 Gbps; you can achieve this rate with packet sizes greater than
128 bytes.
The 320 Gbps switch fabric of the E320 router allocates 10 Gbps of overall bandwidth
to each line module slot. The line interface on the ES2 4G LM when installed in a 320 Gbps
fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes from
64–1518 bytes or a mixture of packet sizes that represent Internet mix traffic (IMIX).
OCx/STMx ATM IOAs
The ES2 4G LM pairs with the ES2-S1 OC3-8 STM1 ATM IOA to deliver unchannelized
OC3/STM1 ATM operation through eight line interfaces. You can install the ES2-S1 OC3-8
STM1 ATM IOA in both IOA bays.
The ES2 4G LM also pairs with the ES2-S1 OC12-2 STM4 ATM IOA to deliver unchannelized
OC12/STM4 ATM operation through two line interfaces. You can install the ES2-S1 OC12-2
STM4 ATM IOA in both IOA bays.
