I do not to suggest you do static TDM dividing timeslots, because this cause bandwidth waste You siimply trunk the PBX together with VoIP and thse will work nicely. Use ISR routers and VWIC or VWIC2 cards for that.
Two additional points, that might be worth noting.
When you share digital voice with data on the same link, QoS often should be configured to insure the digital voice obtains the level of performance it requires.
Depending on the voice codec, it could use more bandwidth then your existing analog voice signal. (I.e. an E1 might not be able to carry as many voice calls.) I recall Cisco recommends not using more than a third of the path's bandwidth for voice. (This I believe so QoS will have the sufficient bandwidth to guarantee the necessary performance.)
"but in your example the link between two routers is ethernet , but in my case its E1 "
Although Narayan mentions Ethernet, there's the additional overhead of IP and the overhead of L2 encapsulation (e.g. HDLC), also on your E1. Narayan also mentions using a compressed codec, but an uncompressed codec like the g711 starts at 64 K before adding L2/L3 encapsulation.
