The Max User Bandwidth available for a radio port configured as an L1 LAG port
member is ninety-five percent of the pre-migration MPT-HL radio port capacity. The
reduction in Max User Bandwidth must be accounted for prior to migration to an L1
LAG port. Failure to account for this reduction in Max User Bandwidth may result in
a loss of all cross-connected traffic after the migration to the L1 LAG port.
TDM2TDM and TDM2ETH services supported by the L1 LAG port require a different
amount of bandwidth then when supported by an MPT-HL radio port. The required
bandwidth for cross-connected services must be recalculated to ensure that the
cross-connected services do not exceed the Max User Bandwidth of the new L1 LAG
port. Failure to confirm that all services are supported by the new L1 LAG port may
result in a loss of all cross-connected traffic after the migration to the L1 LAG port.
For information regarding bandwidth required based upon type of service, see
Table 8. To calculate the required bandwidth for cross-connected services, use the
following equation:
Required Bandwidth = (# DS1 TDM2TDM x 2080) + (# DS1 TDM2ETH x
1882) +
(# DS3 TDM2TDM x 60264) + (# DS3 TDM2ETH x 46571)
Table 8 MPT-HL L1 LAG bandwidth per service type
Type of service L1 LAG bandwidth used [Kbps] MPT-HL bandwidth used [Kbps]
DS1 TDM2TDM 2080 1683
DS1 TDM2Eth 1882 1694
DS3 TDM2TDM 60264 48756
DS3 TDM2Eth 46571 45574
Caution: Migration to L1 LAG port impacts TDM2TDM and TDM2ETH traffic on a per flow-
id basis. Typical impact to traffic is less than 10 seconds for each cross-connection.
The time required for the system to migrate the MPT-HL radio port to the L1 LAG port is
dependent upon radio port provisioning (synchronization, PPP RF, number of; port
segregations, VLANs, and cross-connections). Typical migration duration is less than two
minutes. Allow up to five minutes for the system to migrate all services from the MPT-HL
radio port to the L1 LAG port.
