| SIS Sunny 2M CNV |
| Introduction |
|
| SIS Sunny 2M CNV E1 to V.35 Gateway will replace the traditional way for having Ethernet environment by connecting with DSU/CSU and router. It eases the problems during installation, maintance and is cost effective. Sunny 2M CNV is a broadband interface adapter device, which converts the protocol from E1 to V.35 interface with different E1 Configurations. |

| Clocking Options |
| G.703 Slave Mode |
: |
Derived from received G.703 signal and supplied on V.35 interface, as well as used for encoding the G.703 transmit signal. |
| V.35 Slave Mode |
: |
Derived from V.35 DTE supplied clock and used for encoding the G.703 transmit signal. (external clock accuracy should be +/- 30 ppm) |
| Master Mode |
: |
Internally generated and supplied to the V.35 interface as well as used for encoding the G.703 transmit signal. |
|
| |
|
| |
| Diagnostics |
| V.35 Loop Back |
: |
Activated by front panel switch "V.35 LP" or by asserting "LL" control signal on the V.35 interface. Loops back data received at the V.35 interface to the V.35 DTE. |
| G.703 Loop Back |
: |
Activated by the front panel switch "G.703 LP". Loops back data received at the G.703 interface to the G.703 transmit. |
| Bert |
: |
Activated by the front panel switch "PAT GEN". Generates a pseudo random 2047 pattern as per ITU-T recommendation V.54 and transmits it on the G.703 interface. Simultaneously compares data received on the G.703 interface to the standard pattern and flashes front panel "ERROR" LED once for every bit mismatch. |
|
| |
|
| |
| Front Panel Indicators |
| PWR |
: |
"ON" indicates presence of internal +5V supply. |
| TXD |
: |
"FLICKERING" indicates activity on data received at the V.35 interface. |
| RXD |
: |
"FLICKERING" indicates activity on data sent at the V.35 interface. |
| 703 SYNC |
: |
"ON" indicates that proper data is being received on the G.703 interface. "OFF" indicates absence of signal on G.703 receive pins. "FLASHING" indicates Alarm on G.703 receive signal, owing to absence of code violations. |
| TST |
: |
"ON" indicates activation of
1) V.35 loop, or
2) G.703 loop, or
3) pattern generation and checking. |
| ERR |
: |
"FLASHING" indicates mismatch of receive data on G.703 with respect to a 2047 bit pseudo random sequence conforming to ITU-T V.52. |
