Fusion Call Control Handler
Note 2:
Data speed 64 kbps is used for the T1 or E1 interface. 
Data speed 56 kbps is used for the T1 interface with bit stealing.
Data speed 48 kbps is used for the T1 interface with both bit stealing and the Zero Code
Suppression (or Bit 7 Stuffing).   
Note 3:When a node is set “network,” the distant node over the fusion link should be set “user,” and vice versa.

Fusion Call Control Handler
See the following figure when multiple numbers of FCH circuit cards are connected to a 24DTR as a
cascade connection. 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...

1. General Function
This circuit card provides the repeater function which is based on ANSI/IEEE 802.3. Eight (8) of the
10BASE-T ports are located on a HUB card. 
As seen from the functional connection diagram below, the HUB card is located between the CPR (LANI)
and the FCH card. The HUB card distributes the Fusion link data onto FCH cards.

4. Lamp Indications
Lamp indications for this circuit card are shown in the table below.
Note 1:This lamp is used to indicate the status of the TPn-X port. Therefore, the circuit card operates normally
regardless of the cable polarity.
Note 2:This circuit card can detect data packet collisions at a TPn-X port when it would be a collision of  2048bit-
times (2.048 ms) or when the packet collides 32 times consecutively.  The port is  then...
