Early comment[edit]

The basic argument for this technique is that it provides a guaranteed QoS for a service since resources are physically allocated to the channel and traffic from other channels will have no impact on this channel.

In TDM the channel is divided up into sub-channels. Are the bold channels above sub-channels or the primary DTM channel? 02:31, 5 November 2006 (UTC)

There is only one level of channels in DTM. However there are discussions about introducing a mapping of DTM channels inside a DTM channel ("DTM-in-DTM"). This would have several interesting applications, such as providing VPN like DTM tunnels, off-loading intermediate nodes from signalling etc.

Your use of the term "channel" is a bit missleading in this context. A DTM link has a certain capacity, a number of slots. On this one or more DTM channels can be formed of any multiple of slots, as long as there is slots available on that link. Cfmd (talk) 20:55, 25 September 2012 (UTC)

B-ISDN reborn[edit]

I've been through all this before, and I don't hold out any great hopes for it outside of closed systems; it's swimming against the tide that has already washed away ATM.

As far as I can tell, this is effectively an implementation of CBR "jumbo phone calls" in the spirit of B-ISDN, with 64 bits per timeslot instead of 8, and is effectively an admission of defeat with regard to ATM. (Mind you, it's more likely to be possible to implement correctly.)


  • What's the call setup protocol?
    • DCP (DTM Control Protocol)
  • What's the call routing protocol?
    • DRP (DTM Routing Protocol)
  • What do the call setup and routing protocols run over (for example, are there dedicated signalling timeslots on each path, as in the PDH?)
    • Yes the first timeslot on each link is used for signalling
  • I wonder how long this will take to be deployed encapsulated as DTMoIP?
    • It was introduced in 2009 and is now widely deployed...

Added answers inline to the questions above. Vigaglum (talk) 06:55, 13 October 2012 (UTC)


Besides needing verifiable citations, this needs context. It looks like the article was created circa 2005. So in the six years since, has anyone implemented it? W Nowicki (talk) 22:42, 14 July 2011 (UTC)

It is being implemented and commercially used. The article lacks many relevant quotes, as the reminder of the ETSI series of standards. The deployment is there. The lack of update does however not very well reflect its usage. Cfmd (talk) 20:49, 25 September 2012 (UTC)
