Receive STS-1 Telecom Bus Clock Output – Channel 1;
The exact function of this input pin depends upon whether the
“STS-1 Telecom Bus Interface associated with Channel 1” is
enabled or not, as described below.
If STS-1 Telecom Bus (Channel 1) has been enabled –
STS-1 Receive Telecom Bus Clock Output – Channel 1;
STS1RXD_CK_1:
All signals, which are output via the “Receive Telecom Bus –
Channel 1” are clocked out upon the rising edge of this clock
signal. This includes the following signals.
• STS1RXD_D_1[7:0]
• STS1RXD_ALARM_1
• STS1RXD_DP_1
• STS1RXD_PL_1
• STS1RXD_C1J1_1
This clock signal will operate at 19.44MHz. (For STS-3 mode)
or 6.48MHz (Fro STS-1 mode)
RXVALIDFCS_1 (Receive HDLC block valid FCS Indicator
– Channel 1)
RXGFCCLK_1 (Receive ATM GFC clock signal – Channel
1)
TxP_STPA (Transmit PPP Level 2 Selected Channel
Packet Available)
Receive STS-1 Telecom Bus Clock Output – Channel 2;
The exact function of this input pin depends upon whether the
“STS-1 Telecom Bus Interface associated with Channel 2” is
enabled or not, as described below.
If STS-1 Telecom Bus (Channel 2) has been enabled –
STS-1 Receive Telecom Bus Clock Output – Channel 2;
STS1RXD_CK_2:
All signals, which are output via the “Receive Telecom Bus –
Channel 2” are clocked out upon the rising edge of this clock
signal. This includes the following signals.
• STS1RXD_D_2[7:0]
• STS1RXD_ALARM_2
• STS1RXD_DP_2
• STS1RXD_PL_2
• STS1RXD_C1J1_2
This clock signal will operate at 19.44MHz. (For STS-3 mode)
or 6.48MHz (Fro STS-1 mode)
RXVALIDFCS_2 (Receive HDLC block valid FCS Indicator
– Channel 2)
RXGFCCLK_2 (Receive ATM GFC clock signal – Channel
2)
