Nortel BLN Router T1 Load Balancing? Networkrs 01-10-06

I would like to implement load sharing on the BLN

Scenario:

Core Site:
BLN with 5280 Sync module
Two Separate dedicated T1 circuits to the remote site

Remote Site:
ARN with Tri-Serial

I would like to load share / load balance across both of these point to
point T1 circuits.

Is this possible? and if so how?

there are two ways I do it.

For point to point circuits I use PPP in a multilink PPP bundle.

For Frame, Nortel uses FRF.15 End-to-End Multilink Frame Relay, bundles
at the PVC level. The Multi-link standards are primarily FRF.15 and
FRF.16, but correct operation also involves FRF.5, FRF.8, and FRF.12.
FRF.15 takes an 'end-to-end' approach to Multi-Link Frame Relay. The
aggregate VC can be composed of multiple VCs taking divergent paths
across different Frame Relay switches. This approach is more complex to
implement and must make additional provisions for frames to be
resequenced at the destination. Correct implementation includes use of
the FRF.12 frame fragmentation standard, which may limit the ability of
fragments to leave the Frame Relay environment and be carried over other
services such as ATM. ( Note - Cisco does not currently have
FRF.15-based devices, they do support the FRF.16 standard)
