LANE 2 Capability
LANE servers in M770 ATM switch are capable of supporting LUNI 2.0. By default,
each ELAN supported by the M770 LECS is configured in 'auto' mode, meaning,
that the first LES that registered at the LECS for this ELAN, determines whether the
ELAN would use a LUNI 1.0 or LUNI 2.0 protocol. This ELAN capability is
configurable. For more details, refer to Chapter 16, “Managing an ELAN“. If the
ELAN is determined to use LUNI 1.0 and a LUNI 2.0 Client tries to register, it will
be told to use LUNI 1.0. However, if a LUNI 2.0 is used in the ELAN, and a LUNI 1.0
client tries to register, it will be registered, as the LES is capable of using the LUNI
1.0 protocol as well.

The LECS in an Avaya M770 ATM Switch
•
By default, the M770 ATM Switch will seek a remote LECS at the WKA.
•
The M770 ATM Switch pre-defines one ELAN:
— An Ethernet ELAN named “default”. This is the ELAN name that is
— An Ethernet ELAN named “default”. This is the ELAN name that is
requested by several Avaya’s Ethernet-to-ATM Access Switches.
•
The M770 ATM Switch LECS can support up to 64 ELANs.
•
The M770 ATM Switch enables you to specify default ELANs that will be used
when a LEC does not specify the ELAN name but does specify the type of
ELAN it wishes to join. You can also define a default ELAN that will be used
when a LEC does not specify both the ELAN name and the ELAN type.

The M770 ATM Switch LECS supports a proprietary automatic LES address
determination method to locate a suitable LES for an ELAN.
determination method to locate a suitable LES for an ELAN.
•
All M770 LES will automatically register with the LECS. The benefit of this is
that you do not have to supply the LES address when registering with a M770
LES, and if a M770 LES is re-located you do not have to re-configure the LECS
with the new LES address.

•
The M770 ATM Switch LECS supports a proprietary resilient algorithm to
implement LECS redundancy. On failure of an elected active LECS, resilient
LECSes in standby mode will elect a new active LECS. No disruption in the
working of LANE services in the ATM network will be experienced, providing
all resilient LECS have the same database configurations.
