Typical for the Slot1 and Slot2 page sections, when a PIIC module is present in either or both
slots:
G.703 Configuration
• Interface Type – Use the drop‐down list to select None, E3, T3, or STS1.
• Tx Clock Source – Use the drop‐down list to select Tx Clock, Ext Clock, or Rx Sat.
Comtech EF Data strongly recommends that you select Tx Clock unless a high
stability External Clock is present and timing of the network requires all
devices to be locked to the External Clock.
