2. The MLLN is a Managed Leased Line Network system which provides variable bandwidth leased line connectivity. The State-of-the art technology equipment MLLN is designed mainly for having effective control, on the leased lines so that the down time is very much minimised and the circuit efficiency is increased thus achieving more customer satisfaction. This mainly supports with data circuits ranging from 64 KBPs to 2048 KBPs.

3. MLLN is capable of supporting two types of leased line circuits, 1
MLLN is capable of supporting two types of leased line circuits, 1. Point to Point Circuit  2. Point to Multi Point Circuit 

4. POINT TO POINT CONNECTIVITY
Local and Long Distance Typically, leased lines are used by businesses to connect geographically distant offices. Unlike dial-up connections, a leased line is always active. More than one Local or Long Distance leased circuits converging on a location such that data from one leased circuit can be transferred automatically to another leased circuit for the same subscriber.

5. Features of MLLN Bandwidth management as per the customer demand.
Pro-active maintenance, without waiting for customer to book a complaint .
Self Diagnostic/software loops to check E 1 connectivity to DXC, VMUX/software loops for checking copper pair at NTU point for immediately identifying the faulty section for trouble shooting
Control, Manage the leased line network.
Alternate routing in case of any route failure.
Generation of the periodic performance reports for self-analysis/customer .
Bandwidth management as per customer requirement (64 Kbps and N X 64 Kbps upto 2048 Kbps).
Saving the cost of modems. NTU is provided by BSNL without any charges .
Proactive maintenance

6. ADVANTAGE OF CUSTOMER
Bandwidth management as per customer requirement(64 Kbps and nx 64 Kbps  up to to 2048 Kbps ).
Bandwidth management:  Bandwidth up-gradation shall be allowed.  The down-gradation is not permitted.  For example, a 512 Kbps circuit may be allowed to become Kbps for a minimum 6 hours per day(other 18 hours it may remain as 512 Kbps), but a 512 Kbps circuit cannot be downgraded to 128
Saving the cost of modems.  NTU is provided by BSNL without any charges.
Proactive maintenance
Time dependent bandwidth
Time Dependent bandwidth:-  MLLN system is capable of providing deferential time dependent bandwidth on request.
