Metro Clear

• Metro Clear is a cost-effective layer 2 VPN solution that is designed to provide

multipoint connectivity and allows a customer to have full control over the

networking layer.

• Fibre connection will be managed by Telkom up to and including the NTU. The

customer will be given a wide choice of bandwidths (4-600MB) and will be free to

choose the QoS breakdown of the traffic.

• Service will be delivered on a standard electrical Ethernet port.

• Several classes of service.

Ethernet Express

• High demand for point-to-point solutions.

• Bandwidth is limited in current layer 2 point-to-point solutions.

• Some layer 2 point-to-point services inefficiently use fibres.

• Certain layer 2 point-to-point services have distance limitations.

• Ethernet Express is designed to offer the same and more than

current layer 2 point-to-point solutions.

• Ethernet Express will be capable of offering software upgradeable

bandwidth.

Ethernet

• It is a guaranteed packet-based service.

• Utilises SHDSL.

• Point-to-Cloud Layer 2 service.

• Ethernet interface to customer.

• 64kbs – 2Mbs (Guaranteed).

• Metro Ethernet backhaul.

• From Wholesale perspective, Etherlink will be an enabler for the following

retail products:

o Stand alone point-to-point leased line services.

o Access to IP VPNs, Internet and value added services.

o Access to L2 VPNs, for example Metro Clear. (future)

IP Stream

• Customer pays Telkom for line rental & POTS calls

• With L2TP the backhaul is technology transparent (ME or ATM).

• Services may be provisioned to customers on all Telkom DSLAMs.

• More service layer control …

IP address assignment – the operators can use static IP addresses.

Timeouts – operators have full control over this aspect
