Basic functions

A DXM board can receive and transmit four channels of framed E1 signals, two channels of sub-rate or N x 64 kbit/s signals, eight channels of G.703 64 kbit/s codirectional signals, two channels of G.703 64 kbit/s contradirectional signals, and eight channels of RS232/RS485 signals/RS232-trans/RS422/RS422-trans.

Port working mode

Allows the port working mode to be specified.

• Framed E1: PCM30(CAS) or PCM31(CCS).
• Serial port: DTE, DCE or MASTER

  NOTE:

  • For N×64 kbit/s services and V.35/V.24/X.21/RS-449/RS-530/RS-530A sub-rate services, the port working mode can be set to DTE or DCE.
  • For G.703 64 kbit/s contradirectional services, the port working mode can be set to MASTER.
  • For RS232/RS485/RS422 services and G.703 64 kbit/s codirectional services, the port working mode cannot be set.
  • For RS422-trans and RS232-trans services, the port working mode can be queried but cannot be set.

NMS port

• External ports: DDN1 to DDN20, representing twenty external ports. external interface: E1 1-4 (DB44) and DDN (Anea 96).
  • Framed E1 ports with IDs ranging from 1 to 4, representing E1 ports 1 to 4. The port impedance can be set to 75 ohms or 120 ohms.
  • G.703 64 kbit/s codirectional ports with IDs ranging from 5 to 12.
  • G.703 64 kbit/s contradirectional ports with IDs of 5 and 8.

  • RS232/RS485/RS422 ports with IDs ranging from 13 to 20.

    • Sub-rate ports: asynchronous (0.6 kbit/s, 1.2 kbit/s, 2.4 kbit/s, 4.8 kbit/s, 9.6 kbit/s, 19.2 kbit/s, 38.4 kbit/s and 48 kbit/s).

    • For an RS422 port, five channels of services are supported. DDN13 is in the receive direction and DDN 16 is in the transmit direction of the RS422 port. DDN14 is in the receive direction and DDN 17 is in the transmit direction of the RS422 port. DDN15 is in the receive direction and DDN 18 is in the transmit direction of the RS422 port, Ports DDN19 and DDN20 can receive and transmit RS422 services but the protocol mode must be set to RS449 on the NMS.
    • The over-sampling mode is supported. The serial port rate can be set to 48 kbit/s (X.50), 56 kbit/s (V.110), or N×64 kbit/s. (N ranges from 1 to 31.) The protocol mode can be set to RS232 or RS422 transparent transmission.

      NOTE:

      After the over-sampling mode is set, the port does not support asynchronous PRBS, but supports synchronous PRBS.

  • RS232-trans service ports with IDs ranging from 13 to 20; RS422-trans service ports with IDs ranging from 13 to 15 and 19 to 20.

  • N x 64 kbit/s or sub-rate ports with IDs ranging from 19 to 20.

    Sub-rate ports: synchronous/asynchronous (0.6 kbit/s, 1.2 kbit/s, 2.4 kbit/s, 4.8 kbit/s, 9.6 kbit/s, 19.2 kbit/s, 38.4 kbit/s, and 48 kbit/s) and synchronous (56 kbit/s). The ports can receive and process other types of sub-rate services by means of over-sampling, only if the ports are configured as synchronous and the to-be-receive sub-rate service rate is four or more times of the port access rate.

• Internal ports: 2M-1 to 2M-63, representing 63 E1 internal ports which use timeslots 1-31 (PCM30(CAS) does not support timeslot 16), with port IDs ranging from 65 to 127.

Service processing

• A DXM board can receive/transmit four channels of framed E1 signals, two channels of sub-rate or N x 64 kbit/s signals, eight channels of G.703 64 kbit/s codirectional signals, two channels of G.703 64 kbit/s contradirectional signals, five channels of RS422 signals, eight channels of RS232-trans, five channels of RS422-trans, and eight channels of RS232/RS485 signals. In addition, the DXM board can cross-connect 63 channels of system-side E1 signals, or 64 kbit/s signals.
• Cross-connects 63 channels of system-side E1 signals and 64 kbit/s signals.
• Cross-connects E1 services and sub-rate services as well as 8 kbit/s E1 services but does not cross-connect 8 kbit/s sub-rate services.

  • Synchronous/Asynchronous (2.4 kbit/s, 4.8 kbit/s, 9.6 kbit/s, 19.2 kbit/s and 48 kbit/s) services can be encapsulated in X.50 D3 mode.

Clock

• For the synchronous sub-rate serial port, N x 64 kbit/s services, and G.703 64 kbit/s contradirectional services, the receive and transmit clock edges can be configured.
• DDN1 (first framed E1 port) and DDN19 (the first-channel sub-rate is set to N x 64 kbit/s) can be used as the system clock source.
• The 2 MHz/2 Mbit/s local system clock, DDN19, DDN20, framed E1-1, framed E1-2, VC-12-1, VC-12-17, and VC-12-33 can be used as the intra-board clock source.
