Paradyne 336x E1 manual RS-232-like MIB RFC, General Port Table, RS-232-like MIB

SNMP MIB Objects

When time-slot 16 is reserved for signaling, allocated DTE channels must be mapped to the corresponding network channels (e.g., D1 to N1, etc.), otherwise an error is returned to the SNMP manager.

When time-slot 16 is using Channel-Associated Signaling (CAS), allocated DTE channels can be mapped to any other corresponding network channels (e.g., D1 to N3, D5 to N7, etc.).

RS-232-like MIB (RFC 1317)

The ªrs232º object defined by RFC 1317 is supported for all of the synchronous data ports, the COM port, and the AUX port. The RS-232-like MIB consists of one object and five tables, as follows:

•Number of RS-232-like ports

•The General Port Table

•The Asynchronous Port Table

•The Synchronous Port Table

•The Input Signal Table

•The Output Signal Table

The Asynchronous Port table is not supported by the

E1 NTU for the synchronous data ports. The Input Signal and Output Signal tables are not supported for the AUX and COM ports. The following sections provide clarification for objects contained in the RS-232-like MIB when it is not clear how the object definition in MIB is related to the E1 NTU.

Number of Ports ± ªrs232Numberº Object (rs232 1)

This object contains the number of ports in the RS-232-like general port table. This number is 3 for the 3365 NTU, 4 for the 3360 NTU, and 6 for the 3364 NTU.

General Port Table, RS-232-like MIB

The general port table contains general configuration objects for the RS-232-like interfaces.

General Port Table ± ªrs232PortIndexº Object (rs232PortEntry 1)

This object contains a unique value for each port and is used as an index into the general port table

(rs232PortTable). The values of the rs232PortIndex object vary between models and are listed below.

The values of rs232PortIndex for the 3360 NTU are:

•1 ± COM port

•2 ± Auxiliary RS-232 port

•3 ± DCE port 1

•4 ± DCE port 2

The values of rs232PortIndex for the 3364 NTU are:

•1 ± COM port

•2 ± Auxiliary RS-232 port

•3 ± DCE port 1

•4 ± DCE port 2

•5 ± DCE port 3

•6 ± DCE port 4

The values of rs232PortIndex for the 3365 NTU are:

•1 ± COM port

•2 ± Auxiliary RS-232 port

•3 ± DCE port 1

General Port Table ± ªrs232PortTypeº Object (rs232PortEntry 2)

This object is used to identify the port's hardware type. Only the following values are supported by the E1 NTU.

•other(1) ± Used to identify synchronous data ports that are configured as X.21.

•rs232(2) ± Used to identify the AUX and COM ports.

•rs422(3) ± Used to identify synchronous data ports that are configured as EIA-530A or RS-449.

•v35(5) ± Used to identify synchronous data ports that are configured as V.35.

General Port Table ± ªrs232PortInSigNumberº Object (rs232PortEntry 3)

This object contains the number of input signals contained in the input signal table. This is the number of signals that can be detected. This number is 2 for the

3360-A2-GB20-20 December 1996 E-11
