Cisco IOS XE Cupertino 17.8.1

Channel Associated Signaling (CAS) is a method of signaling each traffic channel rather than having a dedicated signaling channel. CAS uses the same channel, which carries voice or data to pass control signals. This provides an advantage as the implementation of CAS is inexpensive.

Supports CAS feature with "in-band" signaling type. You can configure CAS on a specific interface or under global CEM class.

DS0 loopback is used for testing and troubleshooting the T1 or E1 channel over PSN. You can configure local and remote loopback on channelized T1 or E1 controller (DS0 channel).

If the PSN has several NxDS0 pseudowires that are configured at the TDM side, then the same number of NxDS0 loopbacks can be configured on the controller. This provides better TDM maintenance.

Increased MPLS label scale support

Starting with Cisco IOS XE Cupertino 17.7.1 release, you can further increase the MPLS label range from 32,768 to 40,950 to configure the dynamic label range.

TAP and Split TAP Support for Protected Interfaces

TAP and split TAP support for the following protected interfaces on both receive and transmit direction:

• Automatic Protection Switching (APS)

• Unidirectional Path Switching Ring (UPSR)

• Card Protection Group (CPG)

With this feature support, you can perform monitoring and debugging on these virtual protection interfaces.

Test Access Port (TAP) or Test Access Digroup (TAD)

Support for Test access port or digroup (TAP/TAD) in the following aspects:

• Non-intrusive monitoring for both receive and transmit directions.

• Split and terminate cross connection for intrusive testing in both directions. The TAP feature helps in monitoring and debugging purpose.

RSP-based Non-Intrusive Monitor Ports

This feature allows you to transmit data to multiple connections from a single source using the RSP-based non-intrusive monitor port or Terminal Access Point (TAP) port. It establishes a one-way cross-connect listen connection that listens to either the source or destination of an existing cross-connect or a local connect connection. This feature is only supported on Cisco RSP3 module.

This feature is supported on the following CEM interface modules:

• 1-port OC481/ STM-16 or 4-port OC-12/OC-3 / STM-1/STM-4 + 12-Port T1/E1 + 4-Port T3/E3 CEM Interface Module

• 48-port T3/E3 CEM Interface Module (ASR 900 48-portT3/E3 Interface Module)

• 48-port T1/E1 CEM Interface Module (ASR 900 48 port T1/E1 Interface Module)

• ASR 900 Combo 8-Port SFP GE and 1-Port 10 GE 20G Interface Module (A900-IMA1Z8S-CXMS)

Support for Static MPLS Labels on Cisco RSP3 Module

This feature allows you to provision an Any Transport over Multiprotocol (AToM) label switching static pseudowire without the use of a directed control connection. In environments that do not or cannot use directed control protocols, this feature provides a means for provisioning the pseudowire parameters statically at the Cisco IOS Command-Line Interface (CLI).

This feature is supported on Cisco RSP3 module.

STS1E Framed SAToP Support on IMA3G

Support on clock recovery on STS-1e controller for framed SAToP on the following modes:

• T3

• CT3

• VT-15

BERT Error Injection

BERT Error injection enables you to inject errors into the BERT stream on SONET and SDH controllers. You can introduce BERT errors in a range of 1 to 255.

Support for all 0s and 1s BERT Patterns

Support for all 0s and 1s BERT patterns for SONET and SDH for the following interface modules:

• 1-port OC-192 or 8-9ort Low Rate CEM Interface Module

• 1-port OC-48/STM-16 or 4-port OC-12/OC-3 / STM-1/STM-4 + 12-port T1/E1 + 4-port T3/E3 CEM Interface Module

• ASR 900 Combo 8-Port SFP GE and 1-Port 10 GE 20G Interface Module ( (A900-IMA1Z8S-CXMS)

Cisco IOS XE Amsterdam 17.3.1

Pseudowire Scale Support

A maximum of 26,880 CEM Pseudowires are supported on the Cisco RSP3 chassis using combination of the 1-Port OC-192 or 8-Port Low Rate CEM interface module.
