Introduction
The Cisco IAD2400 Series Integrated Access Devices are fixed configuration multi-service customer
premise equipment (CPE) platforms, targeted at emerging competitive local exchange carriers (CLECs),
incumbent local exchange carriers (ILECs), and inter-exchange carriers (IXCs). The IAD2420 series
enables service providers to cost effectively deploy next generation managed services for the growing
needs of small and medium businesses (SMB) over a single high speed access link. The IAD2400 series
products support both voice over IP (VoIP) and voice over ATM (VoAAL2), with high-density analog or
digital voice interfaces.
The IAD2420 is an IP ONLY platform. It does not support other local area network (LAN) protocols like
IPX, Appletalk, or SNA. Additionally, the IAD2400 series only supports simple gateway control
protocol (SGCP) and media gateway control protocol 0.1 (MGCP). It does not support H.323 or session
initiation protocol (SIP) for voice signaling.
The IAD series is a fixed configuration platform and comes with the required flash memory and random
access memory (RAM) for the operation of the platform. Customers do not need to acquire memory
separately. Table 1 lists Cisco IAD2400 series product numbers with the corresponding WAN and
telephony interfaces.

platform. Table 3 lists the Cisco IOS Release12.1(5)XR2 feature set image for the Cisco IAD2420 series
platforms.

All Cisco IAD2420 series platforms
Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data
encryption feature sets) are subject to United States government export controls and have limited
distribution. Strong encryption images to be installed outside the United States are likely to require
an export license. Customer orders may be denied or subject to delay due to United States
government regulations. When applicable, you must obtain local import and use authorizations for
all encryption strengths. Please contact your sales representative or distributor for more information,
or send an e-mail to export@cisco.com.
Table 4 lists the features and feature set supported by the Cisco IAD2420 series in
Cisco IOS Release 12.1(5)XR2 and use the following conventions:
Note
•
Yes—The feature is supported in the software image.

Important Notes
Important Notes
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload
if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable
password is supplied when requested. This defect can be exploited to produce a denial of service (DoS)
attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers
and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same
defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all
affected IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect,
as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at
http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Product Number Change
Beginning with Cisco IOS Release 12.0(7)XK, Cisco changed the product numbers used to order a
specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train,
maintenance release, and build number. The following table provides some examples.

•
CSCds13360
In a configuration with two Cisco IAD2420's with digital voice ports connected via IP, Channel
Associated Signaling (CAS)-to-CAS calls fail in a “race condition” in which the terminating
gateway receives an answer from the switch before it has forwarded all digits to the switch. This
causes the receiving gateway to generate an error message, stating that it is unable to process the
event error. There is no workaround.
•
CSCds42320
Issuing the Helper CLI ? command (that is, the question mark is the command) after an ip
subcommand under the global configuration mode, the “% Ambiguous command:” is returned. For
example:
uut2(config)#ip audit ? returns the % Ambiguous command: ip audit
The commands themselves work properly as long as the correct syntax is invoked. There is no
workaround.
•
CSCds53207
When making 24 fax-session calls between two Cisco IAD2420's with digital voice ports connected
over T1 in a configuration that includes VoIP, MGCP, E&M immediate, Named Signal Event (NSE),
and codec G.726 32K, many fax-session calls might fail due to the following error code “400 Endpts
in transient state.” The failure rate is about 33% (112 failures out of 336 calls). There is no
workaround.
•
CSCds64525
Under heavy traffic, a call might cause a port to move into a transient state. Even after sending a
“delete connection” (DLCX) message, the port remains in a transient state. There is no workaround.
•
CSCds68259
Under heavy traffic for a long period of time (about six hours), analog calls will cause the following
error message (the date and time will be different):
Nov 10 12:02:20.874: rtpspi_offhook_event: cannot find control block based on
callID -1
There is no workaround.
•
CSCds77162
When the transparent CCS frame-forwarding mode is enabled on controller “T1 1”, after
configuring the CLI commands ccs encap atm and ccs connect ATM0 <pvc> on interface “Serial
1:23”, these two commands also show up on interface “ATM0.” These commands can not be
removed by issuing the CLI command no ccs encap atm or no ccs connect ATM0, but when they
are unconfigured on interface “Serial 1:23”, they also disappear on interface “ATM0.” There is no
workaround.
