Recommendation R.114
Delete existing 5 and replace by the following:
5. International TDM channels to Recommendation R.112 should have the
numbering scheme shown in Table 3/R.114.
6. The numbers assigned to the channels should be selected from the series
applicable to the type of channel and should correspond to its position
in the Figure 1/R.112 to Recommendation R.112.
7. International code independent and code dependent channels to
Recommendation R.102 should have the numbering schemes shown in Tables 3/R.114 and
4/R.114, respectively.
8. The numbers assigned to the channels should be selected from the series
applicable to the type of channel and should correspond to its position in Tables 2
to 4/R.102 to Recommendation R.102.
9. Channel numbering of 50 baud channels for branch-line muldexes conforming to
Recommendation R.1xy should be in accordance with the numbering scheme in
Tables 1/R.114 and 4/R.114.
Add new Tables 3/R.114 and 4/R.114 as indicated:
