Interface Group, MIB II

The interfaces group consists of an object indicating the number of interfaces supported by the unit and an interface table containing an entry for each interface. The T1 DSU/CSU provides an entry in the interface table for the Network T1 interface, the DTE Drop/Insert T1 interface, each of the synchronous DCE data ports (1, 2, or 4 depending on the model), the COM port, and the MODEM port. The following sections provide clarification for objects contained in the Interface Group where it is not clear how the object definition in MIB II is related to the DSU/CSU.

Interface Group ± ªifDescrº

Object (ifEntry 2)

This object provides the textual information about the interface. Set each interface to a text string as specified below:

Network T1:	ªNetwork T1. AT&T Paradyne T1
	DSU/CSU, Hardware Version:
	[CCA number for the CSU
	board]º.
DTE T1:	ªDTE T1. AT&T Paradyne T1
	DSU/CSU, Hardware Version:
	[CCA number for the CSU
	board]º.
COM:	ªCOM port. AT&T Paradyne T1
	DSU/CSU, Hardware Version:
	[CCA number for the CSU
	board]º.
Modem:	ªMODEM port. AT&T Paradyne
	T1 DSU/CSU, Hardware Version:
	[CCA number for the CSU
	board]º.
Data Ports:	ªData Port n. AT&T Paradyne T1
	DSU/CSU, Hardware Version:
	[CCA number for the DSU
	board]º. (where n is between 1 and
	4).

Interface Group ± ªifTypeº Object (ifEntry 3)

This object identifies the type of the interface based on the physical/link protocol(s) immediately below the network layer. Only the following values are supported by the DSU/CSU:

•t1-carrier(18) ± Used for the Network and DTE Drop/Insert T1 interfaces.

•propPointToPointSerial(22) ± Used for the synchronous DCE data ports. Used for the MODEM or COM port when the port is not configured as the SNMP management interface.

•ppp(23) ± Used for the MODEM or COM port when the port is configured for PPP.

•slip(28) ± Used for the MODEM or COM port when the port is configured for SLIP.

Interface Group ± ªifMtuº Object (ifEntry 4)

This object identifies the largest datagram that can be sent/received on the interface. It is applicable only to the interface configured as the SNMP management link. This object is zero for all other interfaces.

Interface Group ± ªifSpeedº

Object (ifEntry 5)

This object provides the interface's current bandwidth in bits per second. The value of this object for each interface is specified as follows:

T1 Interfaces:	1,544,000 bps.
COM and	The currently configured data rate
Modem:	for the port.
Data Ports:	The currently configured data rate
	for the port when the port is
	allocated to one of the T1
	interfaces. If the port is not
	allocated the data rate is defined as
	zero.
