In this menu the operator begins by choosing the composite port to which subsequent menu
operations and commands will be directed. Once this selection is made the command menu
options, 1 through 10 are presented. In this way, the operator may set unique parameters for
Local versus Remote systems, and Composite A versus Composite B.
Some of the menu selections however, automatically update the corresponding parameter on
both Local AND Remote systems. This prevents situations in which the two systems cannot
communicate short of manual intervention at both sites.
4.7.2.1 Composite Link State [1]
This menu allows selection of the enabled/disabled state of the composite link and affects
both the Local and Remote systems. Choosing each option performs the following
commands:
Option [1] : Enable Composite Link.
This command puts the composite link into service. If the remote composite port is physically
connected, the link should synchronize at both ends and begin exchanging data. Any channel
ports allocated to this link will be connected as a result.
Option [2] : Take Composite Link Out of Service.
This command removes the composite link from service. Channel ports allocated to this link
will be switched over to backup channels when configured as such.
4.7.2.2 Composite Link Rate [2]
This menu allows selection of the composite port clock rate. This rate must agree with the
clock provided by the attached DCE, unless timing is derived from the internal oscillator. If the
internal oscillator is selected, the option selected in this menu will force the composite clock
to run at the selected frequency.
The available options are:
Option [1] : 8 Kbps
Option [2] : 16 Kbps
Option [3] : 24 Kbps
Option [4] : 32 Kbps
Option [5] : 40 Kbps
Option [6] : 48 Kbps
Option [7] : 56 Kbps
Option [8] : 64 Kbps
Option [9] : 72 Kbps
Option [10] : 80 Kbps
Option [11] : 88 Kbps
Option [12] : 96 Kbps
Option [13] :104 Kbps
Option [14] :112 Kbps
Option [15] :120 Kbps
Option [16] :128 Kbps
4.7.2.3 Composite Link Type [3]
This menu allows selection of the electrical interface standard to which the composite port will
comply. For V.35, an cable adapter is required.
Option [1]- RS232
Option [2]- V.35
