PA-FCHA
Fusion Call Control Handler
See Figure 3-96 when multiple numbers of FCH circuit cards are connected to a 24DTR as a cascade con-
nection. The FCH can be combined with CCH/DCH on a cascade connection.
One DTI card can have a maximum of five (5) Handler circuits cascaded within the FCH card, the CCH
card, and/or DCH card. Since the FCH card contains one Handler circuit per card, a maximum of five (5)
FCH cards can be cascaded to a DTI card.
As an example, the following (a), (b) and (c) can coexist on a cascade connection.
(a) FCH card (One (1) Handler circuit card per card)
(b) CCH card (Two (2) Handler circuits per card)
(c) DCH card (Two (2) Handler circuits per card)
Also, you must consider the cascading cable length. (

Note:
A maximum cable distance between DTI and the last cascaded FCH (or CCH/DCH) is 50 cm (1’ 7.6 ”).
