5•8•4 T1/E1 Ports

The QFALC framer supports four T1/E1 and contains analog and digital function blocks, which are configured and controlled by MSC8101. Due to its multitude of implemented functions, it fits to a wide range of networking applications and fulfills the according international standards.

External clock oscillator is mounted on the DIP socket to provide easy changing for both T1 and E1. The QFALC reset input is driven by FRMRST~ signal of the BCSR0/5. Due the MSC8101 I/O pins functional limitation, T1/E1 2,3,4 channels are available when Fast Ethernet MII pins will be set to Hi-Z (FETHIEN bit is asserted) and T1/E1 1-th channel is available, when the CODEC is disable (T1_234CODEN is negated) and vice versa. See TABLE 5-6. on page 49.

5•8•5 RS232 Ports

To assist user’s applications and to provide convenient communication channels with both a terminal and a host computer, two identical RS232 ports is provided on the MSC8101ADS, con- nected to SCC1 and SMC1 ports of the MSC8101. Use is done with MC145583 transceiver which generates RS232 levels internally using a single 3.3V supply and has shutdown mode, during which receive buffers are tri-stated. When the RS232EN1 or RS232EN2 bits in BCSR1/6-7 is asserted (low), the corresponding transceiver is enabled. When negated, the corresponding trans- ceiver is enter standby mode, within which the receiver outputs are tri-stated, enabling use of the corresponding port’s pins, off-board via the expansion connectors.

In order of saving board space, 9 pins, female D-Type stacked connector is used, configured to be directly (via a flat cable) connected to a standard IBM-PC like RS232 connector.RS-232 Ports’ Signal Description the list below, the directions ’I’, ’O’, and ’I/O’ are relative to the MSC8101ADS board. (I.e. ’I’ means input to the MSC8101ADS).
