Compact flash connections : One external compact flash sockets will be provided to allow for additional storage and connectivity. It is desirable that the compact flash connection accepts both Type I and Type II compact flash devices.
Serial min DIN: Serial connectivity to a PDA is not required, however a RS232 connection should be provided to allow connection to an external printer or for controlling the device during software updates where Ethernet, USB or other communication is unavailable.
An external 10/100 BT Ethernet port will be provided to facilitate connection to PC's or networks for remote management and software updates and also to provide through testing for applications such as ADSL routed or bridged mode.
Two external USB ports will be provided one configured as a master and one as a slave, both USB ports should conform to the USB 2.0 standard facilitating operation at up to 480Mbps.
The USB port that will be configured as a Slave will use a Type B connector and will be facilitated through a connector on the side of the Goshawk product next to other interface connectors.
The USB port that will be configured as a Master will use a Type A connector and will be facilitated through a connector internal to the Goshawk moulding (See mechanical considerations). This will allow connection to such devices as USB bluetooth or WiFI dongles in order to facilitate wireless connections but without the issue of mechanical damage to these dongles because of them protruding from the Goshawk platform.
A headset and microphone 3.5mm connector will be provided to allow the user to listen to output from the codec in voice applications and also to provide input to the codec in voice applications.
An RJ10 socket connector should be provided to allow connection of the Goshawk tester to the telephone handset connection of POTS or VOIP Soft or Hard Phones.
An RJ11 socket connector should be provided to allow connection of the Goshawk tester to POTS networks or POTS/VOIP adaptors.
would allow the Goshawk to be sold into applications where customers remain sceptical about "blind" one button testing.

OH Capture
Manual
By Trigger Condition
A byte equal to some value
A byte different to some value
Mask
Pre, post or centered
From one to all OH bytes
Up to 200 frames
1 byte per frame
STM-N
6 frames captured if all the OH bytes are captured
200 frames captured if only 1 OH byte is captured
The application of the capture is basically to observe the changes in bits inside the OH bytes transporting alarms or informations (status commands or messages) when some action is supposed to change these bits (e.g. an alarm insertion). The objective is to check a network element is responding appropiately to stimulus. Although in the case of alarms this is ususlly done by observing the response in form of an event, also this should be double-checked at bit level.
In other cases the set of captured frames can show the change in a byte conveying informations such syncronisation messages (byte S1) during the capture period. For example by forcing the switch to a secondary synch source if the quality of clock varies this is indicated by the S1 byte. Again this is to check the correct behaviour of all the multiplexer under test.

29. Tandem Connection Monitoring
The incoming and outgoing data streams (SINK and SOURCE) are each monitored at the network limits.
This allows Operator B to monitor its own errors in the path layer independently of any received errors from Operator A.
Errors here.
Are they coming from A or B?
Operator A
IEC copy

Check

Operator C

Check
N1/N2
here
Path parity errors (BIP) are checked at the input op B network. If errors are present (IEC), they are copied into N1/N2 bytes in the POH. The data now passes through the network of Op B.
At the far end of the network of Op B there is a check made again: Path parity errors (BIP) are checked and compared with the content of extracted N1/N2 bytes.
If there is a difference (BIP different from IEC) the network B produced additional errors. Otherwise, Operator A is responsible for the existing errors.
Multipro SDH helps to monitor the content of the N1/N2 bytes and provides users with easy interpretation of the detailed events.
Operator B
IEC: incoming error count (inside N1)
BIP-2: Bit Interleaved parity (inside N2)
Verdict:
BIP diff IEC Op B generates errors
BIP eq IEC Op B does NOT generate errors

30. Tandem Connection Monitoring
In addition to error monitoring, alarms are also signaled in the backward direction in the same way as in the VCn layer. This allows monitoring of the entire TCM systems in the forward and backward directions
Sink N end Sink F End
TC Alarms-> TC-RDI
BIP diff IEC-> TC-REI
AIS-> ODI
BIP error-> OEI

Operator B

In addition to error monitoring, alarms are also signaled in the backward direction
in the same way as in the VCn layer. This allows monitoring of the entire TCM
systems in the forward and backward directions.
The following events are used to signal alarms:
SOURCE:
Invalid VC-n? --> Insert AIS
BIP errors detected? --> Insert errors in IEC (incoming error count)
Alarms received from SINK -->TC-RDI : Remote Defect Indication
--> TC-REI : Remote Error Indication
--> ODI : Outgoing Defect Indication
--> OEI : Outgoing Error Indication
SINK:
TC alarms detected? -->TC-RDI
AIS detected? --> ODI
BIP errors detected? --> Insert errors in OEI
BIP = IEC? --> Insert difference in TC-REI
monitor the content of
the N1/N2 bytes
TC-RDI : Remote Defect Indication
TC-REI : Remote Error Indication
ODI : Outgoing Defect Indication
OEI : Outgoing Error Indication
