Hermstedt has boosted its line-up of ISDN products with the release of new software and hardware offerings.

First is Angelo, a 30-channel primary rate (PRI) ISDN card aimed at the printing, pre-press and design industries. It allows users to send and receive from multiple sources (Mac or PC) irrespective of file size or type, and offers multi-channel bundling. This enables the card to support multi-link PPP or Leonardo file transfer solutions.

Angelo is a scalable solution - users can start with an 8-channel installation and add more channels according to demand. The card costs £2,500.

Next up is the Leonardo USB, a range of external ISDN adaptors aimed at the professional market. The three models allow fast ISDN communication to digital and analogue terminals using a combination of two or four B-channels and one or four data/fax modems. Prices start at £799.

On the software side, Hermstedt is shipping Grand Central Pro 2.0, an application that manages ISDN file transfer. It automatically recognizes the file transfer protocol of the incoming call, so remote sites don't need to configure any set up. Features include delayed transmission, redialling and secure data transfer supporting hot folders. It also includes an FTP server.
