New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 1700 series routers for Release 12.2(15)ZL.
New Hardware Features in Release 12.2(15)ZL
The following sections describe the new hardware features supported by the Cisco 1700 series routers for Release 12.2(15)ZL.
Two-Port Foreign Exchange Station Voice Interface Card (VIC2-2FXS)
This two port Foreign Exchange Station (FXS) voice interface card (VIC) is a newer version of the existing card that can be used for connecting directly to a standard telephone, fax machine, or similar device, and supplies ring, voltage, and dial tone. The FXS interface is an RJ-11 connector that connects to basic telephone service equipment, key sets, and private branch exchanges (PBXs). Ports on this VIC are color-coded gray.
Two-Port BRI VIC (VIC2-2BRI-NT/TE)
This new VIC provides the BRI network side feature to the Cisco 1751, 1751-V, and 1760 routers as provided by the previous VIC (VIC-2BRI-NT/TE). This feature allows BRI ports on the routers to act as ISDN network-side devices. The NT interface on the router allows the customer to connect ISDN PBXs and key systems to a multiservice network with a minimum configuration changes on the PBX. This module also provides -48V phantom power to PBXs and key switches that require it. The Cisco IOS software replicates the public switched telephone network (PSTN) interface to a PBX that is compatible with the European Telecommunications Standards Institute (ETSI) Net3 and QSIG switch types.
The typical application of BRI-NT allows enterprise customers with a large installed base of legacy telephony equipment to bypass the public telephone network.
This card gives users the flexibility to configure the BRI port to either the user side or the network side. When configured as the network side, the router provides ISDN network-side services. When configured as the user side, the BRI port can be connected to an ISDN network.
The VIC2-2BRI-NT/TE card provides the following benefits:
•
•
•
•
•
•
The VIC2-2BRI-NT/TE VIC can now either source or sync clock from each interface regardless of whether the interfaces are configured as network side or user side. The customer's connection can take a clock source from one port on any of these interfaces (applies to both the original and new hardware) and source that clock to any of the other interfaces. An application of this is to connect one BRI port which would be configured as a user side to the PSTN connection and to then use that clock as the source clock to the other physical ports (which would be configured as a network side) to the connected PBX/private automated branch exchange (PABX). This provides the connected PBX/PABX with exactly the same clock being received from the PSTN, central office (CO), or Post, Telephone, and Telegraph (PTT). The voice port connected to the PSTN, CO, or PTT may be used as a voice gateway connection for inbound and outbound voice calls from and to the PSTN, CO, or PTT in addition to sourcing the clock used to clock another NT port.
•
Each port on a BRI module (VIC and BVM) can support either the NT or TE side. It is possible to support NT and TE on the same module. The consideration is to ensure that clocking is configured correctly.
•
In some testing scenarios, it is necessary to connect a BRI-NT module on one router to a BRI-TE interface in a second router. The only consideration is to ensure that clocking is configured correctly so that no clock collision occurs.
•
The router does not support point-to-multipoint configuration and can provide only one TEI value per BRI port. The router supports automatic TEI but will assign only one TEI (TEI 64) to the TE. The router must support automatic TEI because some PBXs require it even when there is a need to connect only one TEI. When the PBX sends the Link Access Procedure on the D channel (LAPD) ID request, it expects the router to respond to it. Because the router assigns only one TEI, multiple TEs cannot be served. In summary, the router supports the automatic TEI "procedure" but does not provide more than one TEI.
•
Even though the router is acting as the network side, an ISDN phone is not supported and thus should not be connected directly to the BRI ports on the router. Currently the BRI port does not support S-Bus and D-channel collision.
The ISDN switch types currently supported for the network side interface are Basic-NET3 and Basic-QSIG. Other switch types will only be supported as user side.
•
•
Two-Port Ear and Mouth VIC (VIC2-2E/M)
The 2-port E&M (ear and mouth) or receive and transmit (2E/M) VIC is a newer version of the existing card which supports the most common form of analog trunking, the E/M interface. E/M signaling is commonly referred to as ear and mouth or recEive and transMit. E/M signaling defines a trunk circuit side and a signaling unit side for each connection and is similar to the data circuit-terminating equipment (DCE) and data terminal equipment (DTE) reference type. The PBX is usually is the trunk circuit side and the telco, CO, or Cisco voice enabled platform is the signaling unit side.
The two port E&M voice/fax interface card supports 2- and 4-wire interfaces and is used for connecting to the trunk side of the PBX for PBX-to-PBX connections. This card supports 2- and 4-wire, E/M signaling types, I, II, III, and V via RJ-45 connectors.
Note
Two-Port Foreign Exchange Office Voice Interface Card (VIC2-2FXO)
The Cisco 1751, 1751-V, and 1760 routers now support a 2-port Foreign Exchange Office (FXO) VIC that is user configurable with battery reversal for North America, Europe, or Australia. An FXO interface connects local calls to a public switched telephone network (PSTN) central office, or to a PBX that does not support E/M signaling. This is the interface a standard telephone provides. Cisco's FXO interface is an RJ-11 connector that allows an analog connection to be directed at the PSTN's central office or to a station interface on a PBX. The FXO is on the switch end of the connection. It plugs directly into the line side of the switch so the switch thinks the FXO interface is a telephone. This FXO card can also be configured for TBR 21 support. Ports on this VIC are color-coded pink.
Four-Port Foreign Exchange Office Voice Interface Card (VIC2-4FXO)
The Cisco 1751, 1751-V and 1760 routers now support a two port FXO VIC which is user configurable with battery reversal for North America, Europe or Australia. An FXO interface connects local calls to a public switched telephone network central office, or to a PBX that does not support E/M signaling. Cisco's FXO interface is an RJ-11 connector that allows an analog connection to be directed at the PSTN's central office or to a station interface on a PBX. The FXO sits on the switch end of the connection. It plugs directly into the line side of the switch so the switch thinks the FXO interface is a telephone. This FXO card can also be configured for TBR 21 support. Ports on this VIC are color-coded pink.
Cisco 1711/1712 Security Access Routers
The fixed security access routers Cisco 1711 and Cisco 1712 are newly introduced to the family of Cisco Access Routers and include a 4-port 10/100BASET switch and integrated analog modem (the Cisco 1711 router) or the ISDN S/T port (the Cisco 1712 router). The routers provide a complete security solution that delivers IPSec Triple DES (3DES) Data Encryption Virtual Private Network (VPN), firewall, and intrusion detection system (IDS).
ADSL over POTS WIC with Dying Gasp Support (WIC-1ADSL-DG)
The ADSL over POTS WIC with Dying Gasp support (part number WIC-1ADSL-DG) conforms to Cisco WICs/Voice Interface Cards (VIC) and enables ADSL services to be deployed. The WIC supports the Annex A, G.992.1 technical specifications and complies with ANSI T1.413 Issue 2. It targets the business ADSL over POTS service worldwide. The dying gasp support on this ADSL over POTS WIC supports a dying gasp message that is sent by the Customer Premises Equipment Device (CPE — for example, a Cisco 1760 access router with an installed WIC-1ADSL-DG) to the digital subscriber line access multiplier (DSLAM) when a power outage occurs (i.e. the WIC-1ADSL-DG supports DSLAM notification on power loss).
WIC-1DSU-T1-V2
The Cisco WIC-1DSU-T1-V2 is an integrated, managed, T1 or fractional T1 WAN interface card (WIC). It provides non-channelized data rates of 1 to 24 X 64 kbps or 1 to 24 X 56 kbps and follows ANSI T1.403 and AT&T Publication 62411 standards.
The Cisco WIC-1DSU-T1-V2 interface management features include the following:

New Software Features in Release 12.2(15)ZL
The following sections describe the new software features supported by the Cisco 1700 series routers for Release 12.2(15)ZL.
Customizable Tone Download to the Cisco IOS MGCP Gateways from Cisco CallManager
The internationalization and localization enhancements in Cisco CallManager 3.3 require the Cisco IOS Media Gateway Control Protocol (MGCP) gateways to support three to four multifrequency tones and customizable tone download to gateways from Cisco CallManager.
All the Cisco IOS gateway currently support static tones that are pre-defined in the Cisco IOS tone tables. The Custom Tone Download to Cisco IOS MGCP Gateways from Cisco CallManager feature enables the automatic download from a TFTP server of locale-specific tones and their associated frequencies (up to four), amplitude, and cadence information into a custom tone table using XML-based configuration files.
For more details on this feature, refer to the following URL:
Cisco IOS MGCP Gateway Support for Cisco CallManager Network-Specific Facilities
This feature adds Cisco IOS MGCP gateway support for the Cisco CallManager Network-Specific Facilities (NSF). The feature allows users to configure the NSF ISDN information element in the route pattern user interface page. This will enable users to invoke network-specific services and facilities on a call-by-call basis when a user dials the route pattern.
For more details on this feature, refer to the following URL:

Service & Support: Technical Documents: Cisco IOS Software: Release 12.2: Release Notes: Cross-Platform Release Notes (Cisco IOS Release 12.2(15)T)
Important Notes
The following sections describe important notes concerning the new software features supported by the Cisco 1700 series routers for Release 12.2(15)ZL.
VIC2-2FXS, VIC2-2BRI-NT/TE, VIC2-2FXO, VIC2-2E/M, VIC2-4FXO
In some instances, when the command show diag is entered, the message "Unknown field" is displayed. This is due to the fact that in some instances the card information is not pre-programmed for the following voice interface cards:
VIC2-2FXS
VIC2-2FXO
VIC2-4FXO
VIC2-2E/M
VIC2-2BRI-NT/TE
No workaround is in place since this does not affect the functionality of the voice interface cards.
Limitations
The following sections describe limitations concerning the new hardware and software features supported by the Cisco 1700 series routers for Release 12.2(15)ZL.
Four-Port Foreign Exchange Office Voice Interface Card (VIC2-4FXO)
When configured for operation in countries that use TBR21 mode, the use of VIC2-4FXO cards is subject to the following limitations:
•
•
When not operating in the TBR21 mode, these limitations do not apply.
These restrictions do not apply to VIC2-2FXO cards.
ADSL over POTS WIC with Dying Gasp Support (WIC-1ADSL-DG)
The Cisco ADSL WAN interface cards do not support dual-latency, ADSL Plus. When the ADSL link is intended to support both voice and data traffic simultaneously, the link should be configured for either all fast-path data or all interleave data, with an interleave depth of zero to ensure that latency is minimized. In addition, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.
Caveats
Caveats describe unexpected behavior or defects in the Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
Caveats in Cisco IOS Release 12.2(15)T are also in Release 12.2(15)ZL1. For information on caveats in Cisco IOS Release 12.2(15)T, refer to the Caveats for Cisco IOS Release 12.2(15)T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats; the documents are located on Cisco.com and the Documentation CD.
Note
Open Caveats for Release 12.2(15)ZL
The following sections list the open caveats for the Cisco IOS Release 12.2(15)ZL.
•
Workaround
Configure a delay of 300 milliseconds or longer in the device connected to the FXO card to send DTMF digits.
•
Workaround
None.
•
Configuration error history is seen in the show ccm-manager command output after the configuration is downloaded. However, the functionality of the gateways are not affected.
Workaround
None.
•
When either a VIC-4FXS/DID or VIC2-2FXS is connected back-to-back with a VIC-2FXO, pulse dialing from FXO to FXS may not work.
Workaround
None.
Resolved Caveats for Release 12.2(15)ZL
The following sections list the resolved caveats for the Cisco IOS Release 12.2(15)ZL.
•
•
•
Workaround
Set the upstream bandwidth below 512 KB.
•
•
Workaround
None.
•
A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet. BGP MD5 is a valid workaround for this problem.
Cisco has made free software available to address this problem. For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.
