New Hardware Features in Cisco IOS Release 12.1(5) XM
The following new hardware is supported by the Cisco 3600 series for Cisco IOS Release 12.1(5) XM.
2-Port Analog DID Voice Interface (VIC2-DID)
This Direct Inward Dial (DID) voice interface enables a Cisco 3600 series router to provide DID service to extensions on a PBX.
Wireless Network Module
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 3600 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 3600 series routers) for detailed installation instructions, and the Software Configuration Guide (for Cisco 3600 series routers) for an overview of network module configuration procedures and information on configuring specific network modules.
MIX 3660 Module
The Multiservice Interchange (MIX) 3660 module (MIX-3660-64) is used on the Cisco 3660 series to enable the Multiservice Interchange (MIX), which supports switching of DS0 time slots via MIX interconnects across the backplane to each network module slot. This enables the Cisco 3660 series to switch DS0 voice channels on a T1/E1 interface on one network module to and from a separate voice- processing network module.
New Software Features in Cisco IOS Release 12.1(5) XM
The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(5) XM.
Analog DID for Cisco 2600 and Cisco 3600 Series Routers
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.
High Performance Gatekeeper
The High Performance Gatekeeper provides the network administrator the ability to identify H.323 traffic and apply appropriate policies.
The High Performance Gatekeeper is implemented on Cisco IOS software and enables a network manager to:
•

•
MGCP CAS PBX and AAL2 PVC
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.
Multiservice Interchange (MIX) Functionality on the 3600 Series Multiservice Platforms
Multiservice Interchange (MIX) Functionality adds TDM connection capabilities to Cisco 3600 series multiservice platforms. On the Cisco 3660, MIX requires the installation of a multiservice interchange card, also called a "MIX module" (MIX-3660-64). On the Cisco 3620 and Cisco 3640, MIX features are software only. MIX features support applications that are sensitive to time delay, such as voice and video. MIX enables the combination of different types of traffic on a single T1 or E1 connection, giving customers the flexibility to manage traffic through their routers efficiently, as either traditional TDM connections or in packet-based format.
On all Cisco 3600 series multiservice platforms, MIX allows connection of TDM streams between separate voice/WAN interface cards (VWICs) on the same fast Ethernet network module (NM-xFE2W).
On the Cisco 3660, the MIX module also enables the following features:
•
•
•
In addition, extended availability drop and insert (EADI) capabilities have been enhanced to allow MIX connections across slots to stay up through a router reload if they have been saved in the NVRAM.
MGCP Basic CLASS and Operator Services
The MGCP Basic CLASS and Operator Services are 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 is built on the MGCP CAS PBX and AAL2 software package, and 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:
•
•
SIP Diversion Header Implementation for Redirecting Number
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/
SIP Gateway Support for Third Party Call Control
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/
SIP User Agent MIB
The SIP User Agent MIB adds the ability to manage a Session Initiation Protocol (SIP) network via an SNMP-based network management platform.
WT-2750 Multipoint Broadband Wireless System
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.
MIBs
Current MIBs
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Deprecated MIBs
Old Cisco 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 network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 6.
Important Notes
Non-Software Caveats - UNII Configuration
•
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:
–
–
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.

Open Caveats—Cisco IOS Release 12.1(5) XM2
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.
•
An endpoint that is controlled by the Media Gateway Control Protocol (MGCP) or the Simple Gateway Control Protocol (SGCP) might go into a state where notification request (RQNT) message receives the following response, even after retrying the RQNT message several times:
400 Endpt in transient state:Workaround: Reboot the Cisco 3600 router to recover the endpoint.
•
The mapping of the ISDN release code does not follow the documentation as stated in the Enhancements to the Session Initiation Protocol for VoIP on Cisco Access Platforms feature module at http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t3/dtsipgv2.htm. There is no workaround.
•
Hairpinning a call on an HDV module when the call is hung up before being connected causes the "D" channel to go down. There is no workaround.
•
A "B" channel might remain in a "busy" state for an undetermined time after a call is terminated. Eventually the "B" channel is released. There is no workaround.
•
On an outgoing call, the Cisco 3600 router does not map the progress message that it receives. This causes the inband ringback not to be heard. There is no workaround.
•
Using VCON clients, the T120 proxy does not work when a call is established through NetMeeting. There is no workaround.
Resolved Caveats—Cisco IOS Release 12.1(5) XM2
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.
Open Caveats—Cisco IOS Release 12.1(5) XM1
The caveats listed in this section are open in Cisco IOS Release 12.1(5) XM1.
•
This caveat is included because a Cisco 3600 series router can function as a Gatekeeper.
On a Cisco 7200 series router, the Gatekeeper Transaction Message Protocol (GKTMP) may not be able to re-establish connection to the backend server until five minutes after the connection was terminated.
The Gatekeeper sends all requests to the server. However, if there is a slow link or limited processor capacity, the server is unable to respond to these requests on time. When this happens, the Gatekeeper may mark the server as unreachable and terminate the connection. Once the connection is terminated, it will not be re-established for another five minutes.
Workaround: 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.
•
An endpoint that is controlled by the Media Gateway Control Protocol (MGCP) or the Simple Gateway Control Protocol (SGCP) might go into a state where notification request (RQNT) message receives the following response, even after retrying the RQNT message several times:
400 Endpt in transient state:Workaround: Reboot the Cisco 3600 router to recover the endpoint.
•
FXS VIC and DID VIC fail to recognize on-hook.
•
A Cisco 3600 series router functioning as a gateway might modify the ISDN cause code, which is then passed on to the session initiation protocol (SIP) and might cause service to be unavailable. There is no workaround.
•
When a Cisco 3600 series router functioning as a gateway in an SS7 configuration sets up an MGCP connection successfully, and then receives a "delete connection" (DLCX) message before the ringing tone is stopped, or receives any signal which needs a digital signal processor (DSP) resource, the VoIP call is cleared and the telephony call leg is maintained.
However, if a "notification request" (RQNT) message is sent after a DLCX message, the ringing tone stops but the telephony call leg is not cleared. This causes the endpoint to be unable to accept any more calls.
Workaround: Issue the no mgcp command followed by the mgcp command.
First alternative workaround: Make sure the call appearance (CA) sends a RQNT message before a DLCX message.
Second alternative workaround: Make sure the CA sends a DLCX message with"X:<id>".
•
On a Cisco 3600 series router functioning as a gateway, MGCP calls might cause a memory leak. There is no workaround.
Resolved Caveats—Cisco IOS Release 12.1(5) XM1
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.
•
When a call is set up, a large number of lost packets might be reported during the negotiation. Once the call is connected, packets go through properly and counters do not continue to increment.
This caveat has been resolved in Cisco IOS Release 12.1(5) XM1.
•
Connection setup improvements.
This caveat has been resolved in Cisco IOS Release 12.1(5) XM1
Open Caveats—Cisco IOS Release 12.1(5) XM
The caveats listed in this section are open in Cisco IOS Release 12.1(5) XM.
