GL's Octal & Quad T1 E1 boards are high density and provide Four (4) or Eight (8) RJ-48 T1 E1 ports and multiples thereof. For example,
configurations of 8, 12, 16, 64 T1 E1s in a single rack are possible.
- Software Selectable T1 or E1 interfacing along with Drop and Insert
- PCI Express x1 Lane/Board
- Monitor the T1/E1 line conditions such as frame errors, violations, alarms, frequency, power level, and clock (or frame/bit) slips.
- TDM, ISDN, SS7 – High Density Voice
- VoIP, Frame Relay, Multilink Frame Relay, PPP and Multilink PPP, HDLC
- Most all “basic applications” and “special applications” are available for Quad and Octal T1 E1 cards
- Comprehensive Analysis / Emulation of Voice, Data, Fax, Protocol, Analog, and Digital signals, including Echo and Voice Quality testing
- Call Recording, Generation, and Monitoring for hundreds to thousands of calls in one platform
- Windows and Linux Drivers for Open Source Applications
- Media (VoIP) Gateway, IP PBX, and IVR Applications i.e. Asterisk (TM)
- Routing and Bridging emulation over Multi T1/E1 WAN interfaces using MLPPP (Multi Link PPP) and MFR (Multi Link Frame relay) protocols
- Supports “Cross-Port Through” and “Cross-Port Transmit” Modes – these configurations make cabling with Drop/Insert and Fail-Safe Inline
Monitoring very easy
- High Density and High Speed – The boards (with Direct Memory Access) are significantly faster and significantly more efficient
- Octal boards are compatible with dual, quad, and higher core motherboards and software that simulate dual and quad cores (hyper-threading)
- Compatible with Windows® XP , 7 and 8 operating systems and user friendly real-time software

Accompanying Basic Software / Features
GL’s Octal/Quad T1 E1 Analyzer comes with “basic applications” for basic testing needs and “special applications” that extend the capability far beyond the
most expensive T1 E1 Data testers. For example, capturing and transmitting an entire raw T1 E1 signal simultaneously on two full duplex ports, or performing
ISDN emulation, or SS7 analysis, or analyzing echo and voice quality on voiceband channels, to name a few. A list of all the basic applications and other
optional applications (requiring additional licenses) are listed here -
List of T1E1 Basic and Optional Applications With Buyers Guide.
However, some of the applications mentioned below are not supported on Octal/Quad boards:
- ATM Bert
- Bulk delay for error insertion
- Single channel echo / delay emulation
- Protocol classifier
Cross-port Through Loopback
This mode is similar to the standard Outward Loopback except that the signal received on Card 1 (Port 1) is transmitted out onto Card 2 (Port 2). Likewise the
signal received on Card 2 (Port 2) is transmitted out onto Card 1 (Port 1). This feature allows monitoring T1/E1 lines in-line while still being protected from loss of
power to the board. This mode is implemented entirely thru relays and eliminates complex cabling.
Cross-port Transmit Mode Loopback
In this Mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2 (Port 2) and the data that would normally
be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1 (Port 1). The receive paths are completely unaffected. This mode is particularly useful for
Drop and Insert and Error Injection applications in which the board analyzes and may insert traffic running between two pieces of T1/E1 equipment. This feature
also eliminates complex cabling.
