The Router Delay Simulator Plus (RDS+) allows users to test/stage critical DCE or DTE equipment for reliable network operation while simulating network delay times. The RDS+ provides a realistic simulation of physical network behavior with respect to time delays and bit errors. It supports user circuit rates up to OC-1 (51.84 Mbps) while providing delays from zero to a maximum of 8 seconds round trip. Both continuous random and burst errors are supported.

By using the RDS+ in place of or in series with a real data link (WAN) a wide variety of error conditions can be introduced under controlled and testable conditions.

The RDS+ has two data port interfaces that support EIA-644(LVDS), RS-232, RS-422/449, RS-530, V.35, X.21, DS1/E1, TTL, HSSI, DS3, E3, or STS-1. The data interfaces can be mix and matched where applicable, such as V.35-to-RS-530 connection.

Data Clocking can be driven from various sources. It can be provided via the TX and/or RX clocks of the various data port interfaces. Clocking can also be provided from a programmable clock generator internal to the RDS+. An independent external timing source can be used to frequency-lock the internal timing generator via an external timing port on the back of the RDS+.

Data/Control-Lead Delay is programmable in either seconds or number of data bits. Delay may be specified independently to any value on each of the two bi-directional data paths. An option exists to include a control lead on some interfaces with the data delay.

The RDS+ can introduce Random and/or Burst errors into the data stream. These two error types can be used independently or in a combined fashion. The Random error rate is entered as a range
of 1x10-1 to 1x10-12 errors per bit. Burst errors are entered as duration and interval. The error burst duration is from 1ms to 4 seconds and the interval between bursts is from 1ms to 16seconds. The type of error introduced can be the compliment of the data bit, a forced 0, or a forced 1.

The RDS+ contains one BERT generator and one BERT tester. The generator and tester can be independently attached to either data port. When activated the BERT generator replaces the assigned data port data with a standard x9+x5+1 polynomial function to generate a pattern of 511 bits in length. When activated the BERT tester can monitor the data port in either a continuous or a windowed mode. The continuous mode is manually re-triggerable. The windowed mode can be set for a monitor window from 1 to 256ms.

The RDS+ supports digital loopback of either data port. Loopback, Data Delay, Error Simulation, and BERT can all be used simultaneously on a given port. Installation and operation is provided via an operator console port. This port is a RS-232 port that has been tailored for use with HyperTerminal that comes standard with most PCs. RDS+ status and configuration is displayed in real time via this interface. An optional 10Base-T web enabled GUI interface is available for the RDS+.

The RDS+ has a Power LED, one System Status LED and a set of status LED’s for each Port interface, which allow the user to visually confirm the presence of data and clock, and certain control or status signals. The RDS+ is designed with state of the art digital CMOS technology.

The RDS+ is housed in a sturdy 1U high metal enclosure which can be rack mounted. It is powered by an integrated 90-240V 50/60Hz power supply. The RDS+ has a one year warranty and a 24 hour turnaround on warranty repairs.
