Hi every body!
i am just wondering which csu/dsu(brand) is most common in asia and usa?
Thanks a lot!
All current Cisco routers have a slot allocated for internal CSU/DSUs.
The last router NOT to have a slot allocated for internal CSU/DSU was the 2500 Series router which was a non-modular router.
Yes that is what it means. The internal CSU/DSU has the functionality built into the serial card. The CSU/DSU functions take place within the chassis and there is no external unit.
It could be an stand alone unit but if you buy a Cisco router, you often end up with the internal option and it looks like this:
Very hard to tell.
If you purchase a Cisco router, you will most likely purchase an internal CSU/DSU.
However, if you were to purchase a non-Cisco router, you would purchase that vendor's internal offering or purchase a 3rd party external CSU/DSU.
Internal CSU/DSUs are ideal as you can manage/configure them directly from the router.
