Have an SDH ring (STM64).
Need an external synch source (2Mbit/s)
tried to get synch from ESO usning mini BNC but it is not working
With a 2MHz source I am assuming that you are using either ESI-A or ESI-B ports for this. Similar to ESO-A/B, you also have th option to use either a 75ohm (BT43) or 120ohm (DB9) connector. If you need the ESI/ESO 120 ohm DB9 connector pinouts, you can find them in the common Equipment technical documentation (323-1851-102.1). You also have to provision the ESO reference since the NE is to be used for timing distribution. The selected source provides the output timing to both the ESO-A and ESO-B ports. This is Procedure 4-7 Provisioning ESO references from the Configuration-Provisioning and Operating , Part 2 (323-1851-310) technical documentation. From there you can select the timing distribution reference from the drop-down list.
Hi samer, welcome to the Ciena Community! I've moved your question to our 6500 forum. Hang tight while members of the forum review your question and I get in touch with others users of 6500 and our 6500 SMEs. If you have any updates to share on your question, please let us know on this thread.
I am assuming that since you already have an existing SDH ring that you already have some sort of synchronization in the network and you just wanted to extract timing from the ESO port using the 75ohm type BT43 connector.
Procedure 4-6 Provisioning ESO parameters from the Configuration-Provisioning and Operating , Part 2 (323-1851-310) technical documentation will guide you on how to provision the network element for timing distribution.
I hope that this will help you.
Thank you for your reply
Actually I need to get 2Mbit/s synch source out of the OME 6500 using DB9 interface of the access panel.
The SDH ring is synchronized using a 2 MHz source from an Synchronization Source Unit SSU.
This was very helpfull.
please advice from practical point of veiw if we can get 2Mbit/sec ESO from DB9 access panel of one Network Ement in the SDH 64 ring,
while the head node of the ring was synchronized using 2MHz ESI
