Appendix E. Drop and Insert
(Standard and Efficient Options)
E.1 Introduction
Drop and Insert (D&I) functions let a full T1 or E1 terrestrial trunk and a fractional Nx64 Kbps
satellite channel work together.
The framing of the terrestrial trunk is specified in CCITT G.704. The D&I specifications agree with
IBS, small IDR, and Radyne Proprietary Efficient D&I Framing Structures.
The Drop and Insert functions are independent of each other. The Drop function lets you select
the timeslots that are dropped for transmission over the link in the specified satellite channels.
The Insert function lets you select the timeslots into which the received satellite channels are
inserted.
E.2 System Requirements
The unit must have all of these requirements before you can use D&I:
G.703 interface card installed
Open Network Drop and Insert installed
Firmware Revision F05058-AY 6.1 (or later)
Compare the system requirements with the configuration of the unit.
