01-07-2021 06:53 AM. Hi! I'm testing ACR and DCR using an ASR9k on one side and a ASR920 on the other side. Theres a SAToP between them and each end connects to a E1. ACR seems to be Ok, but when I go to DCR I see 2 issues: - I can't find how to configure Differential clock Tx on ASR920. Is it supported?
Mar 22, 2023 Adaptive Clock Recovery (ACR) and Differential Clock Recovery (DCR) are techniques used for Circuit Emulation (CEM) to recover clocks on the following Cisco RSP3 module: NCS 4200 Combo 8-Port SFP GE and 1-Port 10 GE 20G Interface Module (NCS4200-1T8S-20CS)
May 3, 2011 Good morning I'm having problems configuring out of band clocking between two MWR-2941 I have configured one MWR-2941 to Remote recovered-clock slave ! interface Virtual-Cem 0/24 cem 0 xconnect 10.10.10.2 7600 encapsulation mpls network-clock select
Pseudowire-based clocking supports adaptive clock recovery, which allows the Cisco MWR 2941 to recover clocking from the headers of a packet stream. To configure pseudowire-based clocking, see Configuring Pseudowire-Based Clocking with Adaptive Clock Recovery.

I need some help on figuring out how I should setup clocking in the below scenario. In back of this router is UCM Business Edition.
Out-of-band clocking and the recovered-clock command are not supported. Synchronous Ethernet clock sources are not supported with PTP. Conversely, PTP clock sources are not supported with synchronous Ethernet except when configured as hybrid clock.
Network synchronization is supported for Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Modules (NIMs) on the Cisco 4000 Series ISR, by using the network-clock synchronization automatic global configuration command. By default, this command is disabled and user must configure it on Cisco 4000 Series ISR.

The Clock Recovery System is able to recover the service clock using two methods, the Adaptive Clock Recovery and Differential Clock Recovery.
Beginner. 11-12-2007 01:59 AM - edited 03-03-2019 07:30 PM. Can any one Please asssit : I've got a POS link on a 7609 Flexwan Module connecting via a Sonet Network connecting to a remote 12410 GSR. Problem is: i have configured both ends to clock from Line but the OSR keeps reverting back to internal.
Aug 5, 2019 You can configure only a single clocking input source within each group of eight ports (07 and 815) on the T1/E1 interface module using the network-clock input-source command. Multicast timing is not supported. Out-of-band clocking and the recovered-clock command are not supported.

Basic concept. Serial data is normally sent as a series of pulses with well-defined timing constraints. This presents a problem for the receiving side; if their own local clock is not precisely synchronized with the transmitter, they may sample the signal at the wrong time and thereby decode the signal incorrectly.

Mar 3, 2020 Out-of-band clocking and the recovered-clock command are not supported. Synchronous Ethernet clock sources are not supported with PTP. Conversely, PTP clock sources are not supported with synchronous Ethernet except when configured as hybrid clock.
Clock recovery is a common part of many measure-ments, whether as part of the test setup or part of the device under test. Were going to look at clock recovery from a practical point of view, with emphasis on how it affects measurements. This document closely mirrors the poster "The Anatomy of Clock Recovery, Part 1." Why is Clock Recovery Used?
