2 Remove the adapters from the IN and OUT ports. 3 Using the blow brush with the brush removed blow through the ferrule of the

standard ﬂexible connector and the adapter.

CAUTION If the optical ﬁbre of the ﬁxed connector requires further cleaning this entails

disassembly of the module which should only be carried out by suitably trained service personnel.

4 Apply some isopropyl alcohol to a piece of the cleaning paper and clean the barrel

of the adapter. Using a ne w piece of cleaning paper , clean the face of the adapter. Repeat this operation, using a new piece of cleaning paper each time.

5 Lightly press the adhesive side of the tape provided against the front of the

adapter, then remove it quickly - repeat twice. This removes any particles of cleaning paper which may be present.

6 Replace the adapters on the ﬂexible connector.

Pointer adjustment generation

Increment/decrement/alternating:

Provides a burst, selectable between 1 and 10 pointer adjustments (between 1 and 5 for TU-12 or TU-11 pointer).

New pointer value: The AU-4, AU-3, TU-3, TU-2, TU-12 or TU-11 moves to a selectable new location in a single jump, with or without an accompanying new data ﬂag (NDF).

Frequency offset (and 87:3):

Pointer sequences are generated by offsetting the frequencies of the AU-4, AU-3 (in these modes the 87:3 sequence is generated to ITU-T G.783) or TU-3, TU-2, TU-12, TU-11 and the line rate relative to each other. Range: ±100 ppm in 0.1 ppm steps.

ITU-T G.783 sequences: Bursts of periodic single adjustments with added or canceled adjustments. Polarity is selectable. Bursts of periodic double adjustments with pairs alternating in polarity. In all cases the interval between adjustments or pairs of adjustments is programmable. On starting to run any of the pointer sequences an initialization sequence followed by a cool down period may be run prior to the chosen sequence.

User-deﬁned/predeﬁned 16-byte ITUT E.164 sequence. MSOH: K1, K2, D4 to D12, S1, M1, Z1†, Z2†, E2 (and access to bytes reserved for national use plus all bytes reserved for future international standardization). VC-4 and VC-3 POH: J1, C2, G1, F2, H4, F3, K3, N1. J1 path trace: User-deﬁned/ predeﬁned 16-byte ITU-T E.164 sequence or 64-byte sequence. VC-2, VC-12, VC-11 POH: V5, J2, N2, K4. J2 path trace: User deﬁned/predeﬁned 16-byte ITU-T E.164 sequence.

† Z1 and Z2 are not present in STM-0 mode.

Overhead sequence generation:

A single or multi-byte overhead channel is overwritten with a single or repeated sequence of programmed values. The sequence can contain up to ﬁve different values each being transmitted for up to 64,000 frames.

RSOH: 6-byte channel A1A2 3-byte channel D1 to D3 Single byte channels: C1, E1, F1. MSOH: 9-byte channel D4 to D12 2-byte channel K1K2. Single byte channels: S1, M1, Z1†, Z2†, E2.

BER measurement is performed using a 29-1 PRBS inserted into a 64 kb/s channel. Single errors can be added to the test pattern.

MSP message generation:

Messages are displayed in text form as per ITU-T G.783 for linear architecture and to ITU-T G.841 for ring architectures (MSP-ring). User programmed sequences (K1K2).

DCC drop/insert: The data supplied to the DCC port can be inserted into either the regenerator section or multiplexer section data communications channel. Similarly, data can be dropped from either channel. The data may be dropped/inserted MSB or LSB ﬁrst. The data rate for access is: 192 kb/s (RSOH DCC), 576 kb/s (MSOH DCC).

Optical interface stress test:

2 to 259 bytes of the payload are overwritten with a block of zeros or ones after scrambling. Alternatively the ITU-T G.958 CID (consecutive identical digits) test can be selected.

Tributary scan: Automatically test BER on each SDH tributary for error free operation. Rx setup is used to determine tributary structure and test pattern. Alarms: Pattern loss. T est time: Fully user selectable. User selectable bit error threshold: Off, > 0, ≥ 10-3, ≥ 10-6.

Mixed payloads: Backgrounds can be individually conﬁgured to have TU-11, TU-12 or TU-3 independently for foreground testing channel.

Keep alive signals: PDH: T ransmit last conﬁgured SDH signal while

transmitting a PDH signal. SDH: With structured PDH options transmit unframed ﬁxed word PDH signal while transmitting an SDH signal. SDH: Using unstructured PDH option transmit last conﬁgured PDH signal while transmitting an SDH signal.

Thru mode

T ransparent thru mode: The signal is

passed through the instrument without being altered for monitoring purposes where no protected monitor point is available.

Overhead overwrite thru mode:

In addition to the above, the test features associated with the SOH and POH can be enabled to control one single- or multi-byte overhead channel (i.e. errors and alarms, optical stress test, overhead sequences, MSP messages, DCC insert, overhead BER. Full Rx functionality also available).

AU-4/AU-3 overwrite thru mode:

In addition to both of the above, overwrite the complete A U-4/A U3 with the internally generated payload. This enables the SOH to be looped through while a new payload is inserted. All of the test features which affect the VC-4/VC-3 and/or the POH are enabled (i.e. errors and alarms, adjust pointer, overhead sequences, MSP messages, overhead BER. Full Rx functionality also available).

Tributary overwrite thru mode:

When the payload passing through the instrument contains a TU structure, thru mode it will be possible to choose a

2 to 259 bytes of the payload are overwritten with a block of zeros (or ones for NRZ systems) after scrambling. Alternatively the ITU-T G.958 test can be selected.

STM-1 thru mode: Transparent mode: The signal is

passed through the instrument unaltered.

Overhead overwrite mode: The test features associated with MSOH and POH can be enabled in order to control one single or multi byte overhead channel.

AU-4 overwrite mode: Overwrite the complete AU-4 with the internally generated payload.This enables the SOH to be looped through while a new payload is inserted. All of the test features which affect the VC-4 and/or the POH are enabled.

Equalization: Automatic for cable loss up to 12 dB at half the bit rate.

For your protection, review all laser information given in this manual before installing or using the instrument.

WARNING To prevent personal injury, avoid use that may be hazardous to

others, and maintain the module in a safe condition Ensure the information given below is reviewed before operating the module.

Laser Product Classiﬁcation

All Options UH1, UH2, URU, USN, 130, 131 and UKT are classiﬁed as Class I (non-hazardous) laser product in the USA which complies with the United States Food and Drug Administration (FDA) Standard 21 CFR Ch.1 1040.10. Options UH1 and UH2 are classiﬁed as Class 1 (nonhazardous) laser products in Europe which complies with EN 60825-1 (1994). Options URU, USN, 130 and 131 are classiﬁed as a Class 3A laser product in Europe, which complies with EN 60825-1 (1994) / IEC8251(1993). Laser classiﬁcation is based on the ability of the optical beam to cause biological damage to the eye or skin. The EN 60825-1 (1994) deﬁnition of Class 3A is:

”Any laser product which permits human access to laser radiation in excess of the accessible emission limits of Class I and Class 2 as applicable, but which does not permit human access to laser radiation in excess of the accessible emissions of Class 3A and Class 3B (respectively) for any emission duration and wavelength.”

Options URU, USN, 130 and 131 fall into this category, under the EN 60825-1 (1994) (European) standard, because they have a maximum output power of 19.5 mW (under fault conditions), with a wavelength of 1550 nm.

To avoid hazardous exposure to laser radiation, it is recommended that the following practices are observed during system operation:

• ALWAYS DEACTIVATE THE LASER BEFORE CONNECTING

2-10

Page 99

Connecting to the Network

OR DISCONNECTING OPTICAL CABLES.

• When connecting or disconnecting optical cables between the module and device-under-test, observe the connection sequences given below.

Connecting: Connect the optical cable to the input of the device-

under-test before connecting to the module’s Optical Out connector.

Disconnecting: Disconnect the optical cable from the module’s Optical

Out connector before disconnecting from the device-

under-test. Always ensure the shutter closes properly and covers the laser aperture.

• NEVER examine or stare into the open end of a broken, severed, or disconnected optical cable when it is connected to the module’s Optical Out connector.

• Arrange for service-trained personnel, who are aware of the hazards involved, to repair optical cables.

CAUTION 1. Use of controls or adjustments or performance of procedures other than

those speciﬁed herein may result in hazardous radiation exposure.

2. Always leave the ﬁbre optic connector dust caps on each connector

when not in use. Before connection is made, always clean the connector ferrule tip with acetone or alcohol and a cotton swab. Dry the connector with compressed air. Failure to maintain cleanliness of connectors is liable to cause excessive insertion loss.
