ISC SecureLink ISDN Server
Part Number: ISD-SL-1000

SecureLink ISDN Server with PRI Port, Integrated CSU and Ethernet Port.
The ISC SecureLink ISDN Server is the ideal solution for remote LAN access and LAN-To-LAN interconnection. The SecureLink may be equipped with 3 ISDN BRI ports for up to six simultaneous connections or one ISDN PRI port for up to 23 simultaneous connections. Dynamic Bandwidth Allocation providles on-demand multiple B-channel assignment for applications requiring higher throughput than can be provisioned on a single channel. Compression on demand provides another means to increase the throughput of single or multiple B-channels.
With the proliferation of PCs, LANs and bandwidth intensive applications, high-speed connectivity is no longer an exclusive requirement of major data centers. The driving concept behind the SecureLink is to extend the corporate network beyond the traditional boundaries by offering low-cost, high-performance networking to small sites and efficient LAN access to remote users. Restricting remote access is easy with the SecureLink's multiple levels of security (SecurID Card, Mac Address, Caller ID and Host Name).
The ISC SecureLink ISDN Server provides protocol transparency for operations in networks supporting OSI, XNS, TCP/IP, DECNET, Netware and others. The SecureLink includes SNMP Agent and TFTP for downloading new software. The Spanning Tree Protocol provides a fault-tolerant, plug-and-play solution for multi-vendor interoperability.

Sophisticated Filtering
Sophisticated filters can be applied on a Port, MAC address or Pattern basis. The filters reduce the traffic load on the WAN and provide for added security.
Port filters apply to every packet received or transmitted on a specific port. There are Two types of port
filters:
-
- Learned Destination Filters. These Filters do not Forward Packets with Unknown or Learned Destination MAC Addresses. Packets will be Forwarded Only to Statically Configured Endpoints (Hosts).
- Learned Source Filters. These Filters do not Forward Packets with Unknown or Learned Source MAC Addresses. Only Packets From Statically Configured Sourcepoints (Hosts) will be Forwarded.
Static Address filters provide for permanent address filters in the network. These filters can specify:
-
- Directed Output Filters. These Direct Packets to Specific Ports Based on Specific Destination MAC Addresses.
- Source Filters. These Drop Packets with Specified Source MAC Addresses.
- Destination Address Filters. These Drop Packets with Specified Destination MAC Addresses.
Pattern Filters allow filters to be chained together to form multiple conditions (e.g. If this condition AND this condition OR this condition). This is a very powerful filtering mechanism.
