but is now checked by ICMP handlers for attacks and eligibility. If the ICMP traffic matches a NAT rule, NAT will occur on inbound and outbound traffic. HTTP 1.0 requests sometimes caused the firewall HTTP proxy to close prematurely. Cached TCP sessions were sometimes not hit correctly. These issues have been resolved.

PCR: 02242

Module: IPG

Network affecting: No

On a Rapier 24, adding an IP interface over a FR interface caused an

ASSERT debug fatal error. This issue has been resolved.

PCR: 02250

Module: FIREWALL

Network affecting: No

Sometimes the Firewall erroneously used NAT. This issue has been resolved.

PCR: 02259

Module: DHCP, IPG

Network affecting: No

A dual Ethernet router was incorrectly accepting an IP address from a DHCP server when the offered address was on the same network as the other Ethernet interface. An error is now recorded when DHCP offers an address that is in the same subnet as another interface.

DS3 Interfaces

The AT-RP24i/DS3 provides one standards-based unchannelised DS3 interface. The interface has the following features:

■44.736 Mbit/s interface rate, 44.210 Mbit/s payload data rate

■Separate transmit (Tx) and receive (Rx) BNC connectors

■75-ohm impedance

■B3ZS line encoding

■Automatic compensation for lines up to 135m (450ft)

■Loop or internal timing

■C-bit framing

■Support for PPP and Frame Relay encapsulation

The interface meets the following specifications:

■ANSI T1.103, Digital Hierarchy - Synchronous DS3 Format

■ANSI T1.107, Digital Hierarchy - Formats

■ANSI T1.231, Digital Hierarchy - Layer 1 In-Service Digital

■RFC 2496 (DS3 MIB)

Digital Signal 3 (DS3) is a classification of digital signals, and sits at Layer One of the OSI model. The purpose of Layer One is to provide a transmission link between two entities and to monitor the quality of the link. In DS3 the link monitoring is achieved by adding overhead information alongside the data payload.

The DS3 interface rate is 44.736 Mbit/s with a payload rate of 44.210 Mbit/s. The signal is partitioned into Multi-frames(M-frames), and the M-frames are partitioned into seven M-subframes. Each M-subframe is further subdivided
