Data Networks > Branch Connectivity

• An improved error ratio compared to analogue leased lines;
• Higher availability of service due to monitoring of the network;
• Expansion of capacity to cater for future demand;
• International connectivity;
• Higher speed range compared to analogue leased lines.

Because Diginet is a leased line service, you pay a fixed monthly rental regardless of the amount of traffic you send over the link (a dial-up service such as ISDN is billed on the basis of traffic). Diginet would be more economical if you aim to use your data link more than approximately 2,5 hours a day. Other Diginet applications that save time and money include facilities such as videoconferencing.

Installation and transfer times depend on the availability of local infrastructure. Where infrastructure is available, installation/transfer can take from 2 to 4 weeks. Fault repair time depends entirely on the nature of the problem. However, Diginet's fault localising facility ensures that the locations of faults are detected quickly, which considerably reduces repair time.

What standards and protocols apply to Diginet? Diginet is protocol independent. Three different interfaces apply:

• X.21 bis (V.24), a 25 pin interface (speeds of 600 to 19600 bit/s);
• X.21 bis (V.35), a 35 pin interface (speeds of 48 to 64 kbps);
• X.21 (V.11), a 15 pin interface (speeds of 600 bit/s to 1920 kbps).
