Since the launch of their Evolution Modem, engineers at Paradise Datacom have pioneered a host of features designed specifically for Cellular Operators that use satellite links to backhaul Abis traffic. Features such as the Quad-E1 Interface allowed operators to backhaul up to four full or fractional E1 channels at a BTS site with a single modem. Customers wanting to seamlessly migrate from CDMA networks to GSM asked for the ability to bring serial and IP traffic interfaces into the Quad-E1’s internal multiplexer and so – MultiMux was born. Again, Paradise Datacom has raised the bar with the introduction of Sat-Abis, the industry’s only integrated modem and Abis optimizer.
Available in both their Evolution and Quantum series modems, Sat-ABIS provides a simple, cost-effective way to enjoy significant reductions in satellite bandwidth usage for backhaul links without having to purchase expensive and complex outboard components. Sat-Abis was designed from the very beginning to function as a symbiotic element of the existing Paradise Datacom Evolution and Quantum – series modem platforms and consequently works in concert with the litany of powerful features already resident in those products.
Each G.703 port is user-configurable for E1 or T1 traffic, at either full or fractional rates. The on-board multiplexer combines traffic on up to four E1/T1 circuits into a single HDLC packet stream, which reduces encapsulation overhead and packet frequency. Though addressable from the modem’s front panel, the Ethernet ports allow direct PC access for high-speed configuration of the module and provide expansion capability for future applications.
Sat-Abis processes up to 64 DS0 channels (64 kbps) of Abis-compressed voice, signaling and data traffic simultaneously on 1-4 terrestrial E1 ports on the modem’s rear panel. In order to reduce the satellite bandwidth necessary to support the link, Sat-Abis performs the following functions:
- Idle Speech Frames and Idle Data Frames – compression of repetitive data patterns as detailed in Technical Specs 3GPP TS 08.60 for full and enhanced full-rate traffic (sections 3.4 & 3.5.5) and 8.61 for half-rate traffic (section 6.5)
- Idle Data Pattern – compression of Layer-1 Idle Patterns for 64 kbps, 16 kbps and 8 kbps channels as detailed in 3GPP TS 8.54, Layer-1 structure
- Silent Speech Frames – monitoring of Silence Descriptor Indicator (SID) with compression of redundant data (Ref. GSM 06.81)
- Signaling Optimization – signaling is based on LAP-D and is transported as HDLC, which provides more robust transport and reduced bandwidth when compared to fixed-frame encapsulation
- Other TRAU Frames – data is transported in a transparent manner with no optimization or compression.
Though Abis optimization is an excellent first step in maximizing use of the satellite, other technologies may be utilized to take bandwidth savings a step further. In addition to Sat-Abis, Paired Carrier Multiple Access (PCMA) is available as an outboard instrument and will soon be incorporated into the modem as an embedded feature, thanks to an agreement reached between Paradise Datacom and ViaSat, the patent holder of PCMA. PCMA can be used in combination with Sat-Abis for additional OP-EX savings. Other embedded features contained in Paradise Datacom modems include web-accessible diagnostics tools:
- Spectrum Analyzer with peak-hold and multiple bandwidths
- Bit Error Rate Tester – directly compatible with Fireberd instruments
- Constellation O-scope

The Paradise Datacom PCMA-70 boosts the capacity of your satellite transponder space by combining the uplink and downlink transmissions into the same bandwidth.
Slash bandwidth costs and increase the capacity of your satellite networks with the PCMA-70 Series of Bandwidth Saving Satellite Signal Cancellers from Paradise Datacom. This frequency-re-use appliance harnesses the power of patented Paired Carrier Multiple Access (PCMA) technology to cut satellite bandwidth needs by as much as fifty percent.
By simply adding the device to your satellite network, you can expand the capacity of transponders, free up bandwidth for more applications, and lower your network’s operating costs. For example, while satellite space segment costs can vary greatly depending on location and usage, a network operator paying $5,000 per MHz per month for 20MHz can save up to $600,000 per year on bandwidth by using the PCMA-70.
While most satellite transmissions require separate frequencies to transmit and receive, this device enables two different signals to overlap in frequency, which increases the bandwidth available to the system. The appliance uses an adaptive self-interference cancellation technique to subtract your transmitted signal to recover the desired signal. The canceller works with all modulation and FEC techniques on “bent pipe”, non-cross-strapped satellite networks to enhance the benefits of any advanced modulation techniques or turbo coding you may already use.
With a 1RU form factor, the PCMA-70 fits into a standard rack and interfaces with any digital satellite modem. The device cancels signals with bandwidths of 1 to 36 MHz.
