These release notes describe the following topics:

Introduction

This section contains information about the Cisco AS5300 universal access servers and Early Deployment (ED) releases for the Cisco AS5300.

Note The AS5300/Voice Gateway is primarily supported with voice specific IOS releases, namely 12.0(2)XH and 12.0(4)XH. The first planned General Deployment (GD) release for these key Voice over IP (VoIP) features is 12.0(7)T.

The Cisco AS5300 is a versatile data communications platform that performs two functions in a single modular chassis depending on the installed feature cards and IOS images:

The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, as well as medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial access services to digital dial access services.

The Cisco AS5300/Voice Gateway is a versatile data communications platform that provides the functions of an access server, router, and digital modem(s) in a single modular chassis. The AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with modem cards, the AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) Internet access. When equipped with voice feature cards and Voice IOS, the AS5300/Voice Gateway serves as a voice (VoIP) gateway. By using one slot for modems and the other for voice DSPs, the AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the appropriate cards/resources via Dialed Number Identification Service (DNIS).

For information on new features and Cisco IOS commands supported by Release 12.0 XR2, see New and Changed Information and Related Documentation.

Early Deployment Releases

These release notes describe the Cisco AS5300 universal access servers for Cisco IOS Release 12.0(7)XR2. Release 12.0 XR2 is an early deployment (ED) release based on Release 12.0 T that contains fixes to software caveats and support for new Cisco hardware and software features. Other early deployment releases of the Cisco AS5300 are shown in Table 1; unless otherwise indicated, feature support is cumulative from release to release.

There are no new hardware features supported by the Cisco AS5300 for Release 12.0(7)XR1.

New Software Features in Release 12.0(7)XR1

The following new software features are supported by the Cisco AS5300 for Release 12.0(7)XR1:

Cisco H.323 Voice over IP (VoIP) with SS7 for the Cisco AS5300 Access Gateway

The Cisco H.323 VoIP with SS7 feature provides SS7 connectivity for voice gateways by using the signaling controller as a protocol translator to control the gateway using the ISDN Q.931 protocol. This feature interacts over the IP network with other Cisco H.323 VoIP with SS7 solutions functioning as an end-to-end SS7 voice network. In addition, it can communicate with other H.323 endpoints, including gateways using non-SS7 signaling such as ISDN PRI and channelized T1.

The access gateway terminates the PSTN trunks, also referred to as bearer channels, that carry the call traffic. The PSTN trunks are T1 or E1 PRI interfaces. In addition, the access gateway performs call control (including originating and terminating call processing/signaling). The gateway referred to is the Cisco AS5300.

The following enhancements to dial peer configuration limit complexity of dial planning and reduces the amount of effort in creating dial peer entries:

These new dial string symbols are added: period, brackets, percent, parenthesis, plus, and question mark.
**Add table of dial string symbols**
When configuring your dial peers, you are provided with an option called the translation rule. This rule applies a translation rule to a calling party number [Automatic Number Identification (ANI)] or a called party number [Dial Number Information Service (DNIS)] for both incoming and outgoing calls within Cisco H.323 voice-enabled gateways. Also, the rule allows translation of the type of number. Refer to the Q.931 ITU specification for details.
To match on a number type for a dial peer call leg, the numbering-type command is used in dial-peer configuration mode.
Number-type matching is used in dial-peer configuration mode to match on a number type for a dial peer call leg.
When a called number is received and matched to a POTS dial peer, the matched digits are stripped and the remaining digits are forwarded to the voice interface. A new command called digit strip makes this default behavior an option.

Media Gateway Control Protocol for the Cisco AS5300 Voice/Gateway

The Media Gateway Control Protocol (MGCP) provides simple call control functionality in a Voice over IP (VoIP) environment. In this VoIP environment, distributed call agent applications manage calls on trunking gateways.

This feature enables inter-exchange carriers (IXCs) that do not have time division multiplexing (TDM) equipment to provide both long distance services to corporate customers and provide connectivity to local exchange carriers (LECs) and other IXCs that use TDM equipment. This feature also offers IXCs IP networks as an alternative to congested TDM networks.

This feature provides standard MGCP implementing. MGCP will support SNMP through the XGCP-MIB which provides network management for external media gateway control protocols.

This feature also supports TDM hairpinning. Hairpinning allows trunking gateways to route a call back to the public switched telephone network or private or PBX if the IP network is too busy to handle the call. Hairpinning also can be used to connect the public switched telephone network (PSTN) to the network access server (NAS).

Note MGCP supports PBXs using CCS but not channel associated signaling (CAS).

Limitations and Restrictions

MIBs

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 inTable 6:

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

This section only contains open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0(7)XR2.

For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release  12.0 .

For information on caveats in Cisco IOS Release 12.0 T, see Caveats for Cisco IOS Release  12.0  T, which lists severity 1 and 2 caveats and is located on CCO and the Documentation CD-ROM.

Open Caveats---Release 12.0(7)XR2

Cisco IOS Release 12.0(7)XR2 includes bug fixes to Release 12.0(7)XR1. Those caveats from Release 12.0(7)XR1 not closed or resolved in Release 12.0(7)XR2 are still open. Please refer to the "Open CaveatsRelease 12.0(7)XR1" for details on those caveats not closed or resolved in Release 12.0(7)XR2.

Closed or Resolved Caveats for Release 12.0(7)XR2

All the caveats listed in this section are closed or resolved in Cisco IOS Release 12.0(7)XR2.

Basic System Services

If you enter the show interface accounting command on a Cisco router that is running Cisco IOS Release 12.0(3)T, the accounting records are updated only when the first system interface is sampled, and all interfaces share the accounting record of the first interface.

Miscellaneous

When tunneling IPX over an IP tunnel, and when using an extended inbound access list for IP on the tunnel interface, the IPX traffic gets blocked by the access list. As a workaround a permit gre statement could be added in the extended access-list.
When changing traffic shaping parameters in presence of traffic going through, NRP may have a software crash. There is already a fix, but not in 11.3(9)DB2. One may choose to shutdown the interface during configuration update as a workaround.
In Cisco IOS Release 12.0 T, Cisco Express Forwarding (CEF) will not work with bundle virtual circuits (VCs) if you use subinterfaces that are part of the same physical interface.
Received packets which had been padded by the previous hop so as to not be Ethernet runts are corrupted by the MPLS DCEF label imposition code and will result in IP checksum errors at their final destination, or at an intermediate hop, depending on the network configuration. A workaround is to disable DCEF globally or on a per-vip-interface basis.
A Cisco AS5300 was idle because the VSC was in a hung state and RLM along with NFAS was down on the gateway. The gateway flushed on bad ISDN frames and restarted.
When using RLM to connect a Cisco AS5300 access server to a SC2200 running Elan 7, you must configure NFAS on T1 controllers consecutively starting at T1 controller 0. If NFAS is configured on any other combination of T1 controllers, the SS7 CICs on the SC2200 may be blocked upon the restart of TransPath. This can be verified by issuing a rtrv-tc:all command at the mml prompt on the SC2200. All blocked CICs will be identified as BLK=LOCMAN. If you do not use the workaround described above, you must issue a reset-cic command from the mml prompt on the SC2200 for all blocked CICs.
An MGCP call agent can request the Cisco AS5300 to detect the new milli-watt (1004Hz) tone. This is done via the MGCP RQNT command with the requested event being "nm". The problem is that the detection of this milli-watt tone works most of the time, but not 100%.
The disconnect or release message cause value should pass end to end across different networks. If the cause value is equal to UUNSPECIFIED_CAUSE (0x1F), the value will be change to NORMAL_CLEARING (0x10) in the CSM module. To fix this bug, the disconnect cause value will pass end to end instead of change to a different value.
When the destinatination pattern explicity has N number of ".", we expect a match up to the last "." and only forward N digits. Currently, if the called number is longer than the destination pattern, then the whole number is sent. For example: 
    dial-peer voice 100 pots 
destination-pattern 408..... 
port 0:D
If a call comes in via an IP-call leg and the called number is "4085277878", it would match the above dial-peer. However, instead of fowarding 52778, which is what is configured, the entire called number sent is 527878.
Previous to the addition of the new wildcards (%,+,$), this is the behavior and was accepted. However, with the new wildcards, we now have a way to configure for variable length numbers so the explicit matching should now be enforced.

Wide-Area Networking

If there are calls that are up, and the signalling controller (SC) does a switchover, some existing active calls are dropped on the network access server.
Workaround: Upgrade to Cisco IOS Release 12.0(6.5)T7 or higher.

Open Caveats---Release 12.0(7)XR1

This section describes possibly unexpected behavior by Release 12.0(7)XR1 and describes only severity 1 and 2 caveats:

Basic System Services

When utilizing Network Time Protocol (NTP) private mode and control type messages for remote query, a router might reload or you might see traceback messages. There is no workaround.
When utilizing NTP pivate mode and control type messages for remote query it is possible to see a router crash or traceback messages .

Interfaces and Bridging

A Cisco router that is running Cisco IOS Release 12.0(04a) might receive the following alignment error messages on dot1q over Internetwork Packet Exchange service access point (IPX SAP):
%ALIGN-3-CORRECT: Alignment correction made at 0x605B8E70 reading 0x63E5A6F1 %ALIGN-3-TRACE: -Traceback= 605B8E70 60095714 60095700 00000000 00000000 00000000 00000000 00000000
IPX SAP is affected only when dot1q encapsulation is involved (such as when IPX SAP is configured on a dot1q interface).
These alignment error messages do not affect connectivity or cause packet loss. There is no workaround.

IP Routing Protocols

Same global inside address used for three different inside hosts - using dynamic address translation / 11.2.9 IOS.
The following entries might be added to the running configuration of a Cisco router even though Network Address Translation (NAT) is not configured:
There is no workaround.

Miscellaneous

A Multiport Basic Rate Interface (MBRI) might pause indefinitely in "awaiting establishment" and "tei assigned" modes. Entering the clear interface bri <interface number> command establishes multiple frames on the port and allows another ISDN call to be made. There is no workaround.
For Cisco IOS Release 11.2 P or Cisco IOS Release 11.3, packets could be switched in the clear if Fast Ethernet subinterfaces are configured for encryption over encapsulation Inter-Switch Link (ISL), the crypto map is only applied to the main interface, and the IP address is configured in the subinterface. The packets might be dropped when using a Cisco IOS Release 12.0 image while enabling Cisco Express Forwarding (CEF). There is no workaround.
If Token Ring is the endpoint of an encrypted tunnel, extra packets are generated.
Symptoms are a high CPU load (mainly taken by the Crypto Engine) and bogus addresses when enabling the debug tunnel command.
The workaround is to use the interface command tunnel sequence-datagrams on both endpoints of the tunnel.
If devices that can share the same IP address at different times are connected behind an MPC, some Multiprotocol over ATM (MPOA) shortcuts might not be valid after they switch over the IP address. There is no workaround.
The Kerberos Client functionality on Cisco products, when configured to provide access control, will fail in a "deny" state when the expiration of the credentials is in January or February of leap years, thus denying any Kerberos-authenticated access. A workaround for the problem is to choose an alternate form of authentication such as TACACS+ or RADIUS.

Wide-Area Networking

The problem seems to happen only when transferring large amounts of information (ie: ftp).
During that time we see Badsync or Badversion.
When changing traffic shaping parameter in presence of traffic going through, NRP may have a software crash. There is already a fix, but not in 11.3(9)DB2. One may choose to shutdown the interface during configuration update as a wrokaround.
