Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 187
An encapsulation type must be specified in order to distinguish services on
the access port. Encapsulation types must also be specified for network
ports. By default, the encapsulation type for Ethernet ports in network mode
is null.
• Channelized
− Channelized ports can be configured on the 16-port T1/E1 ASAP Adapter
card, 32-port T1/E1 ASAP Adapter card, 2-port OC3/STM1 Channelized
Adapter card, 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card, 8-port
Voice & Teleprotection card (access mode only), 8-port FXO Adapter card
(access mode only), 6-port FXS Adapter card (access mode only), 4-port
DS3/E3 Adapter card (DS3 ports only), 12-port Serial Data Interface card
(access mode only), 6-port E&M Adapter card (access mode only) and
4-port T1/E1 and RS-232 Combination module.
− Configure an access port for customer-facing traffic on which services are
configured.
− Configure a network port for uplink traffic.
An encapsulation type must be specified in order to distinguish services on
the access port or channel. For network mode, the encapsulation type is set
to ppp-auto and cannot be changed.
3.9.3 Maximizing Bandwidth Use
After ports are preprovisioned, multilink bundles (MLPPP) or IMA groups can be
configured to increase the bandwidth available between two nodes.
The following cards, modules, and platforms support multilink bundles:
• 16-port T1/E1 ASAP Adapter card
• 32-port T1/E1 ASAP Adapter card
• 2-port OC3/STM1 Channelized Adapter card
• 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card
• T1/E1 ports on the 4-port T1/E1 and RS-232 Combination module (on
7705 SAR-H)
• T1/E1 ports on the 7705 SAR-A (variants with T1/E1 ports)
• T1/E1 ports on the 7705 SAR-M (variants with T1/E1 ports)
• T1/E1 ports on the 7705 SAR-X
The following cards, modules, and platforms support IMA groups:
• 2-port OC3/STM1 Channelized Adapter card
