The following new hardware features are supported by the Cisco 2600 series for Cisco IOS Release 12.1(5)XM.
This Direct Inward Dial (DID) voice interface enables a Cisco 2600 series router to provide DID service to extensions on a PBX.
The NM-WMDA wireless network module installs in the network module slot of a Cisco 2600 series router. Installing a wireless network module enables the Cisco 2600 series router to act as a subscriber unit (SU) in a point-to-multipoint wireless network. It is configured through the router's system console or via the CiscoView network management system. The network module provides the control and data interface between the Cisco 2600 series digital motherboard and the radio frequency (RF) subsystem in the wireless transverter. It also provides the up/down conversion from baseband to intermediate frequency (IF). One network module supports one or two wireless transverters (main and diversity).
Microcode software images ship in Flash memory along with the system software image. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface linecards.
It is possible to use a later version of microcode software than the one shipped with the Cisco IOS software from the factory. The microcode software in Flash memory is mapped to the linecards. Unless you fully understand how Cisco IOS software uses microcode software, it is important to keep the factory configuration.
The multipoint wireless modem card requires external microcode software. Information about this microcode software is available (with a Cisco.com login) at:
http://www.cisco.com/cgi-bin/tablebuild.pl/rsu.
For further information regarding the network module, refer to the Cisco Network Modules Hardware Installation Guide (for Cisco 2600 series routers) for detailed installation instructions, and the Software Configuration Guide (for Cisco 2600 series routers) for an overview of network module configuration procedures and information on configuring specific network modules.
The following new software features are supported by the Cisco 2600 series for Cisco IOS Release 12.1(5)XM.
Direct Inward Dialing (DID) is a service offered by telephone companies that enables callers to dial directly to an extension on a Private Branch Exchange (PBX) without the assistance of an operator or automated call attendant. This service makes use of DID trunks, which forward only the last three to five digits of a phone number to the PBX. If, for example, a company has a PBX with extensions 555-1000 to 555-1999, and a caller dials 555-1234, the local CO would forward 234 to the PBX. The PBX would then ring extension 234. This entire process is transparent to the caller.
When this feature is configured, a voice-enabled Cisco 2600 and Cisco 3600 series router can receive calls from a DID trunk and connect them to the appropriate extensions.
The High Performance Gatekeeper feature provides the network administrator the ability to identify H.323 traffic and apply appropriate policies.
The High Performance Gatekeeper feature is implemented on Cisco IOS software and enables a network manager to:
The MGCP CAS PBX and AAL2 PVC feature set extends the earlier Simple Gateway Control Protocol (SGCP) CAS and AAL2 support onto the merged SGCP/MGCP software base. These features enable various service provider solutions, including Integrated Access, IP PBX, Residential Cable Access, and Voice over DSL. The added AAL2 PVC features are not implemented in this release.
The MGCP Basic CLASS and Operator Services feature is a set of calling features, sometimes called "custom calling" features, that use MGCP to transmit voice, video, and data over the IP network. These features are usually found in circuit-based networks. MGCP BCOS brings them to the Cisco IOS gateways on packet-based networks.
The MGCP BCOS software supports MGCP 0.1 and the earlier protocol versions Simple Gateway Control Protocol (SGCP) 1.1 and 1.5.
The following MGCP BCOS features are available on Residential Gateways (RGWs):
The following two features can be run as RGW or trunking gateway (TGW) features:
The SIP Diversion Header Implementation for Redirecting Number feature provides support for a new Session Initiation Protocol (SIP) header field; Call Control (CC)-Diversion. The CC-Diversion header field enables the SIP gateway to pass call control redirecting information during the call setup. Call control redirection is the redirection of a call based on a subscriber service such as call forwarding, and is typically used for Unified Messaging and voice mail services to identify the recipient of a message. SIP gateway support has also been enhanced to process a SIP 3xx Redirection response after the receipt of a SIP 18x Information response. More information about this feature is available at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/hennigan.htm
More information about the Session Initialtion Protocol Gateway Call Flows is available at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/
The SIP Gateway Support for Third-Party Call Control feature enables one endpoint (for example, a call controller) to create, modify, or terminate calls between other endpoints via delayed media negotiation. A delayed media negotiation is one where the Session Description Protocol (SDP) information is not completely advertised in the initial call setup. Third-party call control is often used for operator services (creating a call connecting two parties together) and conferencing. SIP gateway support has also been enhanced to allow SIP gateways to route using a Fully Qualified Domain Name (FQDN) in addition to using an IP address. More information about this feature is available at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/caribou.htm
More information about the Session Initialtion Protocol Gateway Call Flows is available at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/
The SIP User Agent MIB adds the ability to manage a Session Initiation Protocol (SIP) network via an SNMP-based network management platform.
The Cisco broadband fixed wireless point-to-multipoint system is an integrated solution consisting of one headend and multiple subscriber units. The fixed wireless point-to-multipoint subscriber unit is designed to receive radio frequency (RF) signals from the headend. It also transmits a return signal to the headend. This return signal is a point-to-point signal, so a properly installed subscriber antenna must be correctly oriented with the headend antenna to which it is transmitting. For more information about the fixed wireless point-to-multipoint headend feature, see Point-to-Multipoint Support for the Cisco uBR7200 Series Universal Broadband Router.
The following sections contain important notes about Cisco IOS Release 12.1(5) XM7 that can apply to the Cisco 2600 series.
A shift in frequency-locked loop (FLL) control voltage causes a 24-MHz reference signal drift on the wireless multipoint network module with diversity (NM-WMDA). As a result, a large-frequency offset occurs in unlicensed national information infrastructure (UNII) outdoor unit (ODU) receive (Rx) and transmit (Tx) oscillators, which are locked on to the 24 MHz reference coming from the NM-WMDA. That causes signal-to-noise ratio (SNR) degradations for both upstream and downstream signals.
The SNR degradation is insignificant in multichannel multipoint distribution service (MMDS) links. However, In UNII links the degradation can be significant, since the local oscillator (LO) multiplication ratio is much higher for UNII frequencies.
Workaround for UNII: The shift in the 24 MHz reference must be minimized by imposing a maximum 2 ms continuous burst size. This is achieved by not using the following slow upstream modulation profiles:
¯ 3 MHz, 4.4 Mbps modulation profiles
In addition to eliminating slow upstream modulation profiles, it is also necessary to set the maximum packet concatenation size to 1522 bytes for all supported modulation profiles. This is done by setting sub-TLV 6 (Maximum Upstream Channel Transmit Burst Configuration Setting), which is part of TLV 4 (Class of Service Configuration Setting), to 1522, which is the maximal number of bytes that can be concatenated. Note that the "Maximum Upstream Channel Transmit Burst Configuration Setting" has to be set for the customer-premise equipment (CPE) to be operational, so the above-mentioned modification is minimal.
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.
| Old Product Number | New Product Number | Release | Image Description |
|---|---|---|---|
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 4.

There are no open caveats specific to Cisco IOS Release 12.1(5) XM7 that require documentation in the release notes.
All the caveats listed in Table 5 are open in Cisco IOS Release 12.1(5) XM7. This table lists only severity 1 and 2 caveats and select severity 3 caveats.
Cisco IOS Release 12.1(5) XM6 does not support the Cisco 2600 series .
Cisco IOS Release 12.1(5) XM5 does not support the Cisco 2600 series .
All the caveats listed in Table 6 are open in Cisco IOS Release 12.1(5) XM4. This table lists only severity 1 and 2 caveats and select severity 3 caveats.
All the caveats listed in Table 7 are resolved in Cisco IOS Release 12.1(5) XM4. This table lists only severity 1 and 2 caveats and select severity 3 caveats.
All the caveats listed in Table 6 are open in Cisco IOS Release 12.1(5) XM3. This table lists only severity 1 and 2 caveats and select severity 3 caveats.
All the caveats listed in Table 7 are resolved in Cisco IOS Release 12.1(5) XM3. This table lists only severity 1 and 2 caveats and select severity 3 caveats.
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5) XM2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
During brief periods of high-traffic activity on the subscriber-unit router and with the router's CPU overloaded, the radio "link-metrics" (continuous codeword error statistics) might not be collected because network-packet traffic has priority over the radio "link-metrics" on the CPU. This might cause the "link-metrics" tables to show zeros only and/or error messages to be generated. There is no workaround.
The system will accept a statistic parameter for a second antenna even though it is a single-antenna system.
Workaround: Disregard data for the second antenna.
When the PPP Password Authentication Protocol (PAP)-password validation fails—that is, when the PPP PAP password is configured incorrectly—a slow memory leak occurs. There is no workaround.
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(5) XM2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(5)XM2.
The caveats listed in this section are open in Cisco IOS Release 12.1(5) XM1.
GKTMP does not retry the backend server for five minutes when the connection is dropped due to link integrity or stress conditions. The problem may occur because of the backend server not being able to keep up with the gatekeeper(s) it is serving. The gatekeeper (GK) will send all requests to the server but because of a slow link or processor capacity, the server does not respond in time. In this case, the GK may mark the server as unreachable and drop the connection. Once the connection is dropped it will not be re-established for another five minutes if there were static triggers configured by the CLI.
Symptom: Server connection is dropped and is not retried for another five minutes.
Workaround: None. Try to match server capacity to process requests with the number and capacities of the gatekeepers it is serving.
The system will accept a statistic parameter for a second antenna even though it is a single-antenna system.
Workaround: Disregard data for the second antenna.
During brief periods of high-traffic activity on the subscriber-unit router and with the router's CPU overloaded, the radio "link-metrics" (continuous codeword error statistics) might not be collected because network-packet traffic has priority over the radio "link-metrics" on the CPU. This might cause the "link-metrics" tables to show zeros only and/or error messages to be generated. There is no workaround.
FXS VIC and DID VIC fail to recognize on-hook.
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(5) XM1. This section describes only severity 1 and 2 caveats and select severity 3 caveats. All caveats that are closed and resolved in Release 12.1(5)T are also closed and resolved in Release 12.1(5) XM1.
A Cisco 2600 series router Signaling Link Terminal (SLT) produces the following message on the console:
* <timestamp>: %PQUICC=1-TOOSMALL: PQUICC(0/0), packet was less than 2 bytes
As a result of this unexpected behavior, the SS7 link goes in and out of service until the SLT is reloaded. There is no workaround.
This caveat has been resolved in Cisco IOS Release 12.1(5)XM1.
The caveats listed in this section are open in Cisco IOS Release 12.1(5) XM.
During brief periods of high-traffic activity on the subscriber-unit router and with the router's CPU overloaded, the radio "link-metrics" (continuous codeword error statistics) might not be collected because network-packet traffic has priority over the radio "link-metrics" on the CPU. This might cause the "link-metrics" tables to show zeros only and/or error messages to be generated. There is no workaround.
The system will accept a statistic parameter for a second antenna even though it is a single-antenna system.
Workaround: Disregard data for the second antenna.
