NEXTEP TLAN - Private Broadband WAN Service by NEC Australia

OAK Telecom is a celebrated reseller for the NEXTEP private broadband WAN network for connecting multiple sites. This is one of the largest Digital Subscriber Line (DSL) networks besides Telstra's in Australia and the one that prides itself in providing the highest quality of service and being the easiest to use. It interconnects with your LAN at layer 2 with an Ethernet interface in the bridging mode for simple installation and operation and is called a Transparent LAN (TLAN) by NEXTEP.

The NEC NEXTEP TLAN network is specifically designed to connect remote offices together to form a seamless Wide Area Network (WAN). A DSL modem is placed in each office, connecting on one side to the local Ethernet LAN through a PC, hub or router. Each modem then connects on the other side to a "DSLAM" using standard existing telephone lines to the local telephone exchange (the DSL connection). The DSLAMs are connected together through NEXTEP’s Ethernet backbone to form a Virtual Private Network (VPN).

The connections formed by NEXTEP’s network do not use the Internet and are made through a Private Ethernet Network with a central intelligent switch.

This network has the following benefits:

• The Private network is completely private and requires no encryption
• No firewalls are required within the Private Network.
• No download charges apply within the Private Network.
• No IP VPN tunnelling is required.
• The connections formed over the network appear to the connected LANs as standard Ethernet ones
• The user administrator can set their own IP addresses within their own LANs at multiple sites as normal and ignore the IP addressing within the NEXTEP core network which is independent.
• Because the traffic is centrally switched within the Ethernet network and each site is associated with a particular physical line, data connections are made only between the sites communicating and not in a "broadcast" mode, so minimising the traffic levels on the network.
• For offices within the same State no distance charges apply.

NEXTEP’s network covers sites in and around capital cities, offering services from 512kbps/128kbps to 20Mbps/1Mbps in ADSL (Asymmetrical DSL) and from 512kps/512kbps to 10Mbps/10Mbps in SHDSL (Symmetrical DSL).

To suit the requirements of different organisations and applications, the services are also supplied in a variety of Contention Ratios (maximum number of users sharing the bandwidth capacity on the backbone). These vary from 50:1 (Remote Grade) to 20:1 (Office Grade) to 4:1 (Server Grade) to 1:1 (Corporate Grade, dedicated).

Prices vary accordingly, allowing users to match the service needed to their budget. For example, the interconnection of PABXs at two sites would require a 1:1 corporate dedicated connection, but a small office with 2 to 3 PCs connecting to the head office LAN would be fine with an 50:1, 512kbps/128kbps connection.

Outside NEXTEP’s coverage area, arrangement has been made to use Telstra Wholesale’s extensive ADSL and BDSL networks to provide extension of the NEXTEP Private Network by using special firmwear in the DSL modem and NEXTEP's own authentication system. The remote office is connected to the Telstra exchange using Telstra Wholesale’s ADSL service (purchased by NEXTEP) and then connected back to NEXTEP’s ATM backbone. This means that Private Networks can be built regardless of whether the offices connected are in the NEXTEP coverage area or not. When using Telstra Wholesale DSL accesses the size of links offered is limited to a maximum of 512kbps/512kbps Symmetrical or 20Mbps/1Mbps Asymmetrical. However, DSL accesses of up to 10Mbps/10MBps Symmetrical are now available through Telstra Wholesale's Business DSL services. Also, ADSL (up to 20Mb/1Mkb) and SHDSL (up to 10Mb/10Mb) accesses from the extensive business grade Optus XYZed network became available from the end of 2006 for connection to the NEXTEP network. With all these options now available an integrated, seamless, economical TLAN network can be set up covering most cities and towns in Australia of interest to business and government clients.

One offering is the "Teleworker", "SOHO" or "Small Office" access with a 512kbps/128kbps DSL connection using the TLAN Private Network to allow remote workers/executives at home or a small office to have a completely private connection to their Head Office LAN for an attractive low price.  These days, however, many companies prefer a Speedmax20Mb/1Mb access as prices are now very attractive with improvements in technology.
