SS7/ISDN Device Drivers

There are two types of SS7 drivers: hardware drivers and network drivers.

Hardware drivers are device drivers that control actual hardware devices to provide SS7 links and other services required by the call control stacks. Hardware drivers are listed under "Hardware Drivers" below.
Network drivers are pseudo-device drivers that emulate an SS7 signalling link using more common IP network connections. Network drivers are listed under "Network Drivers" below.

Hardware Device Drivers

Hardware Device Drivers directly control specialized hardware for SS7, ISDN, SIGTRAN and VoIP. In addition Media Gateway (MG) switching of voice channels can be performed by some cards. A number of device drivers are available including the Sealevel ACB56 ISA card (for V.35), the E400P-SS7 and T400P-SS7 quad E1/T1 span cards, and the E100P-SS7 and T100P-SS7 single E1/T1 span cards. In addition, OpenSS7 SS7 and ISDN stacks can be run embedded on the PTI CPC-388 octal E1/T1/J1 cards.

The current hardware device driver products are listed below. The OpenSS7 SS7 stack has been designed to permit new hardware devices to be easily integrated into the SS7 stack by writing a single low-level driver. If you are interested in a driver for a device that is not listed here, see What hardware is supported? for suggestions.

Historical: The A101c, A102c and A104c are very affordable 1-, 2- and 4-span E1/T1/J1 cards fabricated and sold by Sangoma. This is a good choice for a high-density OpenSS7 SS7 application as these cards will run 96 to 124 SS7 links or voice channels running wide open. Whether you need to set up a large network configuration in the lab, or whether you need to run SS7 in the wild, these boards outperform most offerings in cost and density.

The a100c driver is a high perofrmance driver for the A101c, A102c and A104c single, double and quad E1/T1/J1 cards. The driver can sustain 124 x 64kbps signalling links per E1 card and 96 x 64kbps signalling links per T1 or J1 card. The driver is also capable of interconnecting mu-law and A-law voice channels. In addition the driver can support ISDN D-channels and is capable of switching PRI B-channels.

T400P-SS7, E400P-SS7 Device Driver

Historical: The T400P-SS7 (T1) and E400P-SS7 (E1) are very affordable 4-Span T1 and E1 cards marketed by OpenSS7 Corporation in conjuction with the board fabricator Varion. Proceeds from the resale of these cards funnels back into OpenSS7. This is a good choice for a high-density OpenSS7 SS7 applications as these cards will run 96 to 124 SS7 links running wide open. Whether you need to set up a large network configuration in the lab, or whether you need to run SS7 in the wide open network, these boards outperform most offerings in cost and density.

The x400pss7 driver is a high performance driver for the T400P-SS7 or E400P-SS7 quad T1/E1 cards. The driver can sustain 124 x 64kbps signalling links per E1 card and 96 x 64kbps signalling links per T1 card. The driver is also capable of interconnecting mu-law and A-law voice channels. In addition the driver can support ISDN D-channels and is capable of switching PRI B-channels.

Network Device Drivers

Network Device Drivers do not directly control hardware but provide the same capabilities as a hardware device driver, except that a network service is used instead of a physical link.

The current network device driver products are listed below. The OpenSS7 SS7 stack has been designed to permit new network devices to be easily integrated into the SS7 stack by writing a pushable module. The device drivers listed are for open standard network transports such as Stream Control Transmission Protocol (SCTP) and Service-Specific Connection Oriented Protocol (SSCOP). Proprietary protoocls are not supportable at this time.

SS7 MTP2-User Peer-to-Peer Adaptation Layer

The M2PA device driver is a pushable STREAMS module that can be pushed over a Stream Control Transmission Protocol (SCTP) stream or other transport stream supporting the Transport Provider Interface (TPI).

This is a pseudo-device driver that provides an SS7 signalling link over Internet Protocol (IP) using the Stream Control Transmission Protocol (SCTP).

This network driver is part of the OpenSS7 SIGTRAN stack and allows the SS7 stack to be used without any specialized hardware devices.

IP SS7 Device Driver

The IPSS7 device driver is a pushable STREAMS module that can be pushed over a User Datagram Protocol (UDP) stream or other connectionless transport stream supporting the Transport Provider Interface (TPI).

This is a pseudo-device driver that provides an SS7 signalling link over Internet Protocol (IP) using the User Datagram Protocol (UDP).

This network driver is a part of the OpenSS7 SS7 stack and allows the SS7 stack to be used without any specialized hardware devices.
