■LAN filtering rate: 10000 frames per second.

■LAN forwarding rate: 4000 frames per second.

ISDN and WAN forwarding rates are dependent on the link speed.

Approvals

This product ostensibly complies with the electro-magnetic compatibility (EMC) requirements of EN 55022 Class A and EN 50082 (susceptibility). However, to fully comply with Class B of EN55022 the following prerequisites should be observed:

■The WAN port must be attached to a screened digital cable.

■The ISDN cable must be used in conjunction with a three turn ferrite.

The product carries the CE certification mark to indicate conformance with the following EU directives:

■LVD (Low Voltage Directive (Safety) 73/23/EEC.

■EMC (Electro Magnetic Compatibility) Directive 89/336/EEC.

■TTE (Telecommunication Terminal Equipment) Directive 91/263/EEC.

The product conforms to I-CTR3 (based on NET3 – ISDN interface).
