Vanguard Networks Daughtercards
Daughtercard
Compatibility
Older Vanguard Networks Daughtercards do not fit into the Vanguard 3400 Series.
You can only use the newer daughtercards which are identified by a dimple as shown
in Figure 2-5. If the dimple is not present, do not attempt to use the Daughtercard in
the Vanguard 3400 Series.
Also, when installing a Vanguard Networks Daughtercard into a 3400 Series, you
must use the shorter two-sided header. The taller header is used with other Vanguard
Networks units.

Caution
If you attempt to force an older Vanguard Networks Daughtercard into a Vanguard
3400 Series, the equipment will be damaged.
If you have an older Vanguard Networks Daughtercard and would like to use it in a
Vanguard 3400 Series, contact your service representative about having the card
reworked.
56K DSU/CSU
Daughtercard
The 56K DSU Daughtercard provides an RJ48S connector and can support speeds of
56 kbps (synchronous). It conforms to AT&T 62310 point-to-point and multipoint,
and to ANSI T1/E1.4/91-006 56 kbps. The card supports the following capabilities:
• Internal/external clocking
• Internal/external loopback
• 4-wire line driver operation
The card also supports multidrop DSUs when either of these conditions exist:
• If a MARK Idle protocol is used (such as MX25).
• If the Telco uses an OR'ed or Data Contention is used to mix individual DRU
drops.
Figure 2-7 shows the 56K DSU/CSU Daughtercard connector as it appears on the
